When I use the term ninedigital in these articles I always refer to a strictly zeroless pandigital (digits from 1 to 9 each appearing just once).

More Ninedigital Powers
by Peter Kogel

" Hi Patrick,
Herewith is another pandigital 'project' that I investigated some while ago.

Notable results include:

213452 + 87962 = 532978641

The first term contains 1...5 and the second term contains 6...9.

25382 + 176492 = 29432 + 175862 = 317928645

Only example where two sums are equal.

5393 + 2463 + 7183 = 541623987 5393 + 4623 + 7183 = 625348179

The above is what I call a 'pandigital amicable pair' (see below).

274 + 354 + 684 + 1494 = 516297843 274 + 354 + 864 + 1494 = 549617283

Only one term on the left hand side is different.

95 + 175 + 265 + 435 + 585 = 816725493

Only example for 5th power.

Kind regards,
Pete Kogel. "

Observations

There are only 5 examples where A or B appears in more than one solution: viz ¬

There are several examples where simply swapping two digits in A leads to a member of another solution ¬
E.g.:

4359 4395

5469 5496

5679 5697

In the solution above, A contains the digits 1...5 and B contains the digits 6...9

The above is the only example where N is duplicated.

P = 3 A³ + B³ + C³ = N

A, B & C combined and N are zero-less pandigital.

While looking through the above list I noticed that some values occur in more than one solution
and I wondered whether I could chain several such solutions together; wherein the last number
becomes the first number in the next link: e.g. ¬

(123, 465, 897)
          (897, 321, 564) 
                    (564, 182, 379)

A slightly longer chain would be ¬

(193, 468, 572)
          (572, 381, 469)
                    (469, 153, 728)
                              (728, 693, 145)
                                        (145, 296, 873)

The longest chain that I found consists of 24 members ¬

(172, 348, 596) , (596, 871, 342) , (342, 785, 196) , (196, 273, 458) , (458, 271, 639) ,
(639, 875, 124) , (124, 389, 576) , (576, 831, 429) , (429, 671, 835) , (835, 194, 627) ,
(627, 581, 493) , (493, 786, 512) , (512, 649, 378) , (378, 215, 496) , (496, 278, 351) ,
(351, 792, 468) , (468, 193, 572) , (572, 381, 469) , (469, 153, 728) , (728, 145, 693) ,
(693, 418, 725) , (725, 613, 489) , (489, 317, 526) , (526, 918, 374)

This chain was found by 'hand' so it is possible that I may have missed a longer chain.

While searching for the above I came across the following nine-member 'pandigital sociable group'
i.e. the last member can be chained with the very first member.

	(124, 389, 576) (576, 831, 429) (429, 671, 835) (835, 627, 194) (194, 376, 825) (825, 146, 397) (397, 621, 458) (458, 271, 639) (639, 875, 124)

There is also one example of a 'pandigital amicable pair'.

(539, 246, 718)
          (718, 462, 539)

(123, 564, 879) & (124, 639, 875)
  |    |    |       |    |    |
(231, 465, 897)	& (142, 396, 857)

(231, 456, 789)

(394, 561, 728) = (394, 394+167, 394+167+167)

P = 4 A⁴ + B⁴ + C⁴ + D⁴ = N

E.g.:

A, B, C & D combined and N are zero-less pandigital.

There are only 5 solutions; viz ¬

The second and third solutions shown above are particularly noteworthy (another 'pandigital amicable pair').

P = 5 A⁵ + B⁵ + C⁵ + D⁵ + E⁵ = N

The above is the only solution.

P ⩾ 6 A^P + B^P + C^P + D^P + E^P + F^P + ... = N

No solutions.

The Unique Pandigital 3816547290
by John Morse

" In the header of this message is 3,816,547,290 which is the only 10-digit
pandigital number whose first N digits are a multiple of N. I first discovered
that in The Dictionary of Curious and Interesting Numbers by David Wells,
and I wrote an explanation of how one could figure out that is the number.

John Morse
Albany New York USA "

Mathematics Puzzle

Find the one and only 10-digit number such that :

This explanation is my own, but I first learned about the amazing
mystery number (381,654,729) in an entertaining book, one of my ten
favorite math-themed books of all time :

Procedure

Let the letters A thru J stand for the digits of the number. Then :

A B C D E F G H I J is the mystery number, whereas :

AB is evenly divisible by 2,
ABC is evenly divisible by 3,
ABCD is evenly divisible by 4,
ABCDE is evenly divisible by 5,
ABCDEF is evenly divisible by 6,
ABCDEFG is evenly divisible by 7,
ABCDEFGH is evenly divisible by 8,
ABCDEFGHI is evenly divisible by 9,
ABCDEFGHIJ is evenly divisible by 10.

A number is evenly divisible by 10 only if its last digit is zero.

Hence, we have found right away that J must equal zero, since the
ten-digit number ends in that digit J.

What about divisibility by 9 ? This particular number takes care of that
matter because its nine-digit 'fragment' ABCDEFGHI must use one each of
digits 1 thru 9, and the sum of the nine digits is 45, which is a multiple of 9.

A number is evenly divisible by 9 if the sum of its digits is 9 or a
multiple of 9 itself. Hence, ANY arrangement of the digits 1 thru 9
(or 0 thru 9), each digit used exactly once, will always result in the
number being a multiple of 9.

A number is evenly divisible by 5 only if its last digit is a five or
a zero.

Since all the digits of ABCDEFGHIJ are different, we cannot use zero
since J already has that value.

The first five digits of the entire number are ABCDE, hence digit E
must be 5.

So far, the mystery number looks like this :

A B C D 5 F G H I 0

Even numbers only are evenly divisible by even divisors, e.g., if you
want to divide some number N by 2 or 4 or 6, etc., that number N must
be even since dividing an odd number by an even number will always leave
(an odd) remainder.

Hence, consider the mystery number's even-numbered digits. They
correspond to letters B, D, F, and H. Since zero is being used for J, the
even digits 2, 4, 6, and 8 must correspond to those other four letters.

Therefore, the remaining letters in the number - A, C, G, and I - must
stand for odd digits.

Because the odd digit 5 is already in use via the letter E, A can only
be 1, 3, 7, or 9. The same restrictions apply to C, G, and I.

There are many ways that AB is evenly divisible by 2 : merely let B
equal 2 or 4 or 6 or 8. Hence, there are too many possible ways so
far to assign digits for A and B. How about ABC, which must be a
multiple of 3 ?

The digits A + B + C must add up to a multiple of 3, and in this
instance, B is the only even digit. Hence, the following trios are possible
for fragment ABC :

Eighteen possible permutations exist for ABC; it looks like a lot of
trial and error lies ahead if we test all these 3-digit groups in
combination with the remaining digits for D, F, G, and H. (It does not
matter yet what digit I must be, since the entire 9-digit number up to I
is already divisible by 9.)

However, note that the four-digit fragment ABCD must be a multiple of 4,
and this is possible only if the number formed by the last two digits -
here, CD - is a multiple of 4.

Since C is odd, D can only be 2 or 6. If we try 4 or 8 instead for D, then we
get numbers such as 18, 34, 78, or 94 - none of which are evenly divisible by 4.

A similar situation arises for the 8-digit fragment ABCDEFGH. Since G
is odd, H can only be 2 or 6. A number is divisible by 8 only if its
last three digits (here, FGH) is evenly divisible by 8.

So, between them, D and H use up the digits 2 and 6. We are not sure
which letter will have which digit, but we can eliminate the 3-digit
fragments above where B happens to be 2 or 6, leaving these possible
permutations for the digit group ABC :

Good. Number of permutations is now only eight instead of eighteen.

Since B and F must be even, they must use the only remaining even
digits - 4 and 8 - between them. Let's take a look at the mystery
number where we assign the digits 2 and 6 to D and H and the digits
4 and 8 to B and F :

Consider the six-digit fragment ABCDEF. Its digits must add up to a multiple
of 3. All multiples of six are even, but we already know that F must be even.

Since the digits ABC add up to a multiple of 3, so must those in fragment
DEF. Since E is 5, only two possibilities exist for digits in DEF :

So, we can eliminate two of the four 10-digit numbers above, leaving :

Let's take another look at the 8-digit fragment ABCDEFGH and see if we
can determine whether F must be 4 or 8.

If D=2, then B must be 4, F must be 8, and H must be 6. Since FGH must
be a multiple of 8, it could only end in the following three digits :

Of these four 3-digit numbers, 836 and 876 are NOT multiples of 8, so
eliminate them, leaving only 816 and 896 for FGH.

If D=6, then B must be 8, F must be 4, and H must be 2. Since FGH must
be a multiple of 8, it could only end in the following three digits :

Of these four 3-digit numbers, 412 and 492 are NOT multiples of 8, so
eliminate them, leaving only 432 and 472 for FGH.

Hence, possible arrangements of digits in the mystery number could be :

Recall that fragment ABC must be a multiple of 3. In choice [1], the
only available digits for A and C are 3, 7, and 9. No combination of
these digits will enable ABC to be a multiple of 3, so eliminate choice [1].

For choice [2], the only digits available are 1, 3, and 9. No combination
of these will make ABC a multiple of 3, so scratch choice [2].

For choice [3], the only digits left are 1, 7, and 9. The only workable
combination that will make ABC a multiple of 3 is when neither A nor C
is 7, so I must be 7.

For choice [4], the only digits available are 1, 3, and 9. Digits
1 and 3 may represent A and C, in which case I must be 9. If digits
1 and 9 stand in for A and C, then I must be 3.

So, two choices for the mystery number were removed, leaving these
possible configurations for the mystery number :

Almost there! Each of these six numbers is such that the number AB is
divisible by 2, ABC by 3, ABCD by 4, ABCDE by 5, ABCDEF by 6, ABCDEFGH
by 8, ABCDEFGHI by 9, and ABCDEFGHIJ by 10.

What about the fragment ABCDEFG ? Is it divisible by 7 ? Test each of
the six numbers above using their first seven digits :

[1] 1896543 divided by 7 leaves remainder 5. nope.
[2] 9816543 divided by 7 leaves remainder 2. nope.
[3] 1836547 divided by 7 leaves remainder 6. nope.
[4] 3816547 divided by 7 leaves remainder 0. YES !
[5] 1896547 divided by 7 leaves remainder 2. nope.
[6] 9816547 divided by 7 leaves remainder 6. nope.

Aha! Only choice [4] leaves no remainder when its fragment ABCDEFG is
divided by 7.

Finally we found the mystery number ! It is

Are all the digits different ? Yes. A number with that property is
known as "pandigital". The prefix "pan-" means "all".

How about divisibility of the first N digits by N ? Check and see :

38 divided by 2 = 19, no remainder. Yawn.
381 divided by 3 = 127, no remainder. Okay.
3816 divided by 4 = 954, no remainder. Okay!
38165 divided by 5 = 7633, no remainder. Big deal.
381654 divided by 6 = 63609, no remainder. Good.
3816547 divided by 7 = 545221, no remainder. Good!
38165472 divided by 8 = 4770684, no remainder. Great!
381654729 divided by 9 = 42406081, no remainder. Of course.
3816547290 divided by 10 = 381654729, no remainder. Wonderful!!!

There is no other 10-digit number whose first N digits are evenly
divisible by N - and where every digit occurs once !

Nine and Ten digit squares
by Peter Kogel

" I've had a fascination for numbers and rec maths ever since I first read
Martin Gardner's column in Scientific American many years ago. My particular
fascination is for nine and ten digit number patterns and I've found your
excellent website the source of much inspiration.

This project has been to investigate patterns along the lines of 99066^2
( 9814072356 ) and have found some interesting results that you might like.

Some highlights

77772277772 = 60485271895340361729

The square contains each digit 0...9 twice and the square root is a rather
particular palindrome.

42539071862 = 1809572634_7102438596

The lefthand side is pandigital and the square on the righthand side contains
the digits 0...9 repeated in each half (there are two other such examples).

Nine and Ten digit squares

It is well known that the square of 11826 ( 139854276 ) contains all the digits 1...9
and that the square of 32043 ( 1026753849 ) contains all the digits 0...9.
Others have investigated cases where the digits in the square are repeated more than once.
I have extended this investigation up to the 6th repeat of the digits. My findings are shown below.

I haven't yet found the largest example where all ten digits are repeated 6 times.
Perhaps someone else can find it and perhaps extend the table even further.

While searching for the above I came across the following interesting pair:

A and B differ by only two digits!

Pandigital squares

It is well known that the squares of A = 57321 and B = 60984 each contain all ten digits
and that 'A & B' combined also contains the ten digits. I wondered whether such results
could be extended such that 'A & B' contain the digits repeated twice. I very soon found
literally hundreds of solutions of which the following type is of interest:

Note that the squares of 'A' & 'B' each contain all ten digits repeated twice,
'A' contains no digit larger than 5 and 'A & B' combined contains all ten digits repeated twice.
There are many other such examples.

There are also many examples where 'A' and 'B' are pan-digital. E.g.:

Similarly the following are pan-9-digital

While searching for these examples I came across the following remarkable trio:

Notice that the digits 0...9 are contained in each 'half' of the square
on the right hand side. There are no pan-9-digital equivalents.
[ Tom Marlow discovered only the first two squares. He submitted it to Ed Pegg's
Mathpuzzle site. Source material added 26 January 2003.]

Palindromes

There are many examples where N is a palindrome.

I have not found any solutions where the square is also a palindrome
and I suspect that none exist.

Higher powers

It is natural to ask whether the above results can be extended to higher powers.
The answer is of course "yes!"

E.g.

In the following, the notation (N, P, D) means that the digits 1...9 (or 0...9)
are repeated 'D' times in the value of N^P.

Nine digit examples:

The challenge above was to make 'D' as small as possible for any particular 'P'.
I also have constructed a table of smallest and largest of any particular type
up to and including P = 15.

There are also examples where P = D in viz:

Nine digit examples:

I have not yet found any example where P = D = 7 and I suspect there are none
because it becomes increasingly unlikely that the power of any number will not
contain a zero when P is large.

Ten digit examples:

I have not checked any power larger than 15 as yet.

Pandigital powers

There are a few examples where 'N' is pandigital.

Nine digit examples:

Ten digit examples:

There do not appear to be any examples for higher powers.

A curious pan-digital example is the following

Notice that the left hand side including the index contains the digits 0...9 and that the right hand side
contains the digits 1...9 repeated 3 times. I have found no other such example for any power.

Palindromes

To date I haven't searched for palindrome solutions for cubes and higher powers
but I have no reason to believe that they do not exist. I'll investigate further when
I have a bit more time.

" I used Yuji Kida's excellent UBASIC for all my calculations. The
program I wrote is not very elegant (I am only an amateur programmer)
and the algorithm I developed is probably far from optimal. Indeed,
from what I have learned from this project I would probably tackle it
from a completely different angle if I were ever to do it again. "

Solutions for ABC + DEF = GHI
Linda Rojewski

Linda Rojewski asked for all the combinations of a three digit number added
to a three digit number to equal a three digit number. You can only use digits 1-9,
and can not use any number twice. You can add to carry over a number of which
this number would not count as usage of that number.

Solution:
I (pdg) used the well known UBASIC tool and the result is listed below.
In total there are 336 solutions though not all are unique!
124 + 659 = 783 is listed as well as 659 + 124 = 783.

Question:
From this list it should be easy to extract only the distinct solutions.
How many do you count ?
Send them in and I will highlight them.
