Palindromes in bases 2 and 10.
The main source for this table comes from the following weblink.
Binary/Decimal Palindromes by Charlton Harrison (email) from Austin, Texas.
See also Sloane's sequences A007632 and A046472.
" I just finished writing a distributed client/server program for finding these numbers, and I currently
have it running on 4 different machines at the same time and I'm finding them A LOT faster. That's how
I was able to come up with those new ones. I'd say there are more to come in the near future, too."
[ December 1, 2001 ] Charlton Harrison once found this record binary decimal palindrome 110 0010111100 0010101010 1101000011 1010000010 0000101110 0001011010 1010100001 1110100011 7475703079870789703075747 The binary string contains 83 digits ! |

"Using a backtracking solver, I have found larger numbers.
The first of these, which is the next after the one mentioned above, is
50824513851188115831542805 (86 bit, 3*5*11*11*17*17*83*11974799*97488286319).
There are no other 86 bit double palindromes.
I also have found two 89 bit double palindromes, but I am not sure if they
are the next ones. There may be some lower ones in 89 bit (haven't searched

When asking
Dw for an explanation or description in a few words
what he meant by '
Using a backtracking solver' he replied :
"A backtracking solver is one that solves a problem made up of smaller
problems by trying every one except if it knows its earlier guesses make all
later ones depending on them impossible.
For instance, if you're in a maze and know that all corridors with green
walls eventually lead to a dead end, you can turn around as soon as you find
such a wall (backtrack) if you're trying to find the exit.
The smaller problem is avoiding a dead end, and the larger one is
finding the exit.
If you want the details:
My general strategy goes that to find a double palindromic number, the
solution to its palindromic decimal representation minus its binary
representation must be zero (since they are equal).
Furthermore, you can write a decimal palindrome like 101 * a + 10 * b, where
a and b are digits. The same can be done for binary, and you end up with a
giant (linear diophantine) equation of positive decimal and negative binary factors.
The factors can then be solved, one at a time, using the extended euclidean
algorithm. These are the smaller problems.
I also have a table of maximum and minimum values for each step. That way, if
it's impossible for the binary factors left to subtract enough from the
decimal factors to get zero (or the other way around), the solver backtracks."

Dw (
email) found a new Binary/Decimal Palindrome :
"I have been trying to find a polynomial time (growth of time needed is a
polynomial of number of bits) algorithm for finding double palindromes of
base 2 and 10. I haven't succeeded yet (my backtracking solver being
exponential), but I have found some interesting things.
For one, to find double palindromes in base 2 and 8 is very simple. Each base 8
digit maps to three bits. Therefore, every double palindrome must consist
of digits who themselves are double palindromes.
For instance, 757 as well as 575 is double palindromic. (These values are 495
and 381 in decimal respectively).
5 maps to 101 in binary, and 7 to 111 in binary.
I have found 1609061098335005338901609061 (91 bits composite),
and this is the only 91 bit one. No 92 bit double palindrome exists, and
93 bits seems to require several days of searching; therefore I'm trying to
find a polynomial time algorithm as mentioned above.
Another approach could be to create a networked version (to do the search on
multiple computers), but I haven't done that yet."

That list is exhaustive at D=57.
I'll probably get round to running D=58, 59 and 60 at some stage. Though that is the limit of tractability
short of some number theoretic breakthrough. I believe Eshed's code will do D=55 in about 3 days or so --- I have
got that down to about 10 hours. D=57 took over 40 hours -- D=58 will be similar --- D=59 and 60 will take about
8 days each --- I may or may not bother LOL - I do have a life outside of this stuff that needs my computer time.

Hi Patrick,
D=64 is 3.5 hours into running as I type this. I'm just running into the fundamental limitations of my computer now.
D=65/66 would be 7 days each -- and I have tried every clever trick I can think of -- I have said that before and improved
things but I feel there is only so much you can do with 32 GPU cores and 64GB of RAM.
I still have T=117 and T=119 to do on ternary/binary -- anything beyond that is unlikely. I stopped decimal/ternary at
D=50 --- that is a hard case to push further as well.
As I come to the end of these palindrome searches I hope I have been of some help -- it's fun trying to push a laptop

Dear Mr. De Geest,
I would like to ask you for updating the table re. numbers that are palindromic in bases 10 and 16.
I did some progress on it, and found 51 new members of the sequence. See indices 84 up to 134.
Full list of new members is in the text file in the attachment.
Thank you,

When I asked
Richard how he achieved his results he replied:
I was inspired by Eshed Schacham's nice article:
"Finding Binary & Decimal Palindromes"
The method is useful for powers of two bases (2,4,8,16).
For now I do not plan other bases. It took me 3 days of
experimenting (programming) and 2 days of running (CPU time).
If you are interested in I am sending you my piece of code
in C language (palindrom.c) with external function in assembler
allowing multiply two 64-bit integers into 128-bit value.
Now I must go on with my real job, programming of course :)

Eshed Schacham's article can be found following this link:
https://ashdnazg.github.io/articles/22/Finding-Really-Big-Palindromes
As a software developer he also made public his .c code he wrote for this topic and explains the algorithm in great depth.
To my surprise he found 35 new decimal palindromes that are also palindromic in base 2 or binary.
I added them forthwith to my webpage. Please refer to indices 148 up to 183 in the very first
scrolltable of this very page. Impressive if you consider their record lengths.

Dual-base Palindromes
[ do 2/5/2024 6:02 ]
Hi Patrick,
I am sending you in the attachment several
new records for dual-base palindromes:
base 10 & 3: 4 new records → From [71] to [74]
base 10 & 4: 35 new records → From [65] to [99]
base 10 & 5: 100 new records → From [84] to [183]
base 10 & 6: 9 new records → From [110] to [118]
base 10 & 7: 8 new records → From [74] to [81]
base 10 & 8: 43 new records → From [89] to [131]
base 10 & 9: 5 new records → From [71] to [75]
base 10 & 16: 9 new records → From [135] to [143]
Thank you for this interesting entertainment.
For bases 10 & 4, 10 & 8 and 10 & 16 I used practically the same method as I mentioned earlier.
For base pair 10 & 5 I used very similar method, main difference is that solutions don't fit into
128-bit (it prunes much faster) so I rewrite the code using GMP library (GNU multiple precision).
For the rest of base pairs I used optimized brute force method, where I generate all possible
palindromes in one base and check it in another one. In cases where one base is power of 2
it is pretty straightforward (just bits comparison).
In all cases (except 10 & 5) I employ possibility of Intel processor to multiply two 64-bit integers
into 128-bit value (rdx:rax) and division of this 128-bit value into quotient and remainder
(instructions mul, div).

Dual-base Palindromes (bases 10 & 5)
[ do 5/8/2024 16:44 ]
Hi Patrick, Hi Eshed,
I am here again, I would like to ask you for updating dual-base
palindrome sequence A029962 (bases 10 & 5), where I found 52 new
members (in the attachement). I improved algorithm a bit, but it
is still far from optimal. Changing bases to 10 & 2 I can not
achieve Eshed's records at all. Basic idea remains the same.

Dual-base Palindromes (bases 10 & 5)
[ do 30/10/2025 19:01 ]
Hi Patrick,
I am sending you in the attachement 42 new members of OEIS sequence
A029962 (numbers simultaneously palindromic in bases 10 and 5).
base 10 & 5: 42 new records → From [236] to [277]
I used the same algorithm as the last time plus some optimization
and longer running time (two weeks).

Dual-base Palindromes (decimal & ternary)
[ do 5/4/2026 11:50 ]
Submitted entries [75] up to [99] for the base 3 (ternary) case.
Being a number theorist, my coding skills are not exactly top level developer code.
I started looking at this problem trying to create a constructive algorithm for these numbers
as opposed to an exhaustive search approach - I am pretty sure the list I gave is exhaustive - but
I haven't proven it as of yet. R.

Dual-base Palindromes (decimal & ternary)

Submitted entries [111] up to [117] for the base 3 (ternary) case.
This ends my search short of a number theoretic breakthrough - D=41 and 42 would just
take too long - this is a more difficult task than searching for decimal/binary where D=55
can be done in a couple of days or so. R.J.
The only one that really holds my interest is ternary/binary - also a difficult programming task -
current record has T=91 digits (T is ternary) - but Nikulshin states on OEIS they must have
checked T=93 as well. See Simultaneous palindromic in bases 2 and 3.That's actually quite
impressive since it was done over a decade ago on weaker hardware. There must be some
pruning trick I am missing though - just like him and Astrelin (now deceased) must have done
for their decimal/binary code - I know they go to 50 digits with that on old hardware - with
small memory - I know the Eshed code can run D=55 in a few days on modern hardware but that
runs into requiring tables of a large size which becomes impractical for D>55 - the Nikulshin
approach can use far smaller tables - in fact DRAM latency for large tables is a big factor in
limiting what you can do on realistic hardware. R.J.

More dual-base Palindromes (decimal & ternary)
[ zo 24/06/2026, 22:00 ]
Submitted entries [125] up to [131] for the base 3 (ternary) case.
I have finished doing decimal/ternary so that one value at D=45 is it for me -- the scaling has
finally worn out and the runs are getting too long - as I said a full D=45 run will take 11 days
which is not feasible for me.
So please note this D=45 is not an exhaustive list -- and all I can say is that the number above
is the smallest at D=45 --- I only found it because I was doing a quick run to determine
the time for a complete run and that one happened to pop out in the first 4 minutes of what
would be a 11 day run.

Richard

Submitted entries [132] up to [143] for the base 3 case (decimal/ternary).
Hi Patrick,
Also --- I gave you a single palindrome for decimal/ternary at D=45. I have done D=45 completely plus
D=46,47,48. (I have done D=49 and it was blank BUT there is a slight chance, which I am investigating,
that it could have missed solutions at D=49 or above so I am holding off, on declaring that finished).
…
…
So we have completed
dec/tern to D=48
and also
six/bin to S=80
tern/bin to T=115

More decimal/ternary
[ vr 16/08/2026, 14:25 ]
Submitted entries [144] up to [150] for the base 3 case (decimal/ternary).
Hi Patrick,
I did have a problem for missing solutions at D=49 and D=50 for decimal/ternary. All D up to and thru 48
were correct -- I had a parameter going silently out of bounds for D=49 and above.
All fixed now.
So instead of being empty - D=49 has 7 solutions:
…
…
But D=50 is genuinely empty. So the next solution is > 10^50

Hi Patrick,
…
…
I stopped decimal/ternary at D=50 --- that is a hard case to push further as well.
As I come to the end of these palindrome searches I hope I have been of some help -- it's fun trying to push a laptop
as far as I think is possible on brute force number crunching.

Decimal/Base X duals
[ do 3/09/2026, 15:52 ]
Hi Patrick,
I have done all the ones on your page that were not extended already by dedicated codes.
So I am attaching the solutions up to D=40 for the decimal/baseX for baseX = 4,6,7,8,9,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36 and 60.
Also -- here are the primes in each list with obvious notation:
…
…
All of the solutions were verified once in Rust and once in Mathematica --- all primes were verified by the ProvablePrime package for Mathematica.
I will probably extend these to D=45 some time.
Hope this helps.
Regards,
Richard
ps
If you have any problem with these being corrupted let me know and I'll send them individualy

Hi Patrick,
You have that gaping hole between base 36 and base 60 that says "missing tables planned for construction in the future"
Seems like an open goal for bases 37 to 59 and all in between.
So here they are all to D=40 digits.
Here are the primes in those lists:

There, lots of fun for you.

Hello Patrick,
Inspired by latest achievements in dual base palindrome
search I improved my base 10/5 algorithm again:
I do not use GMP library, I do computation directly in base 5,
because base conversion is too slow...
And I moved to Linux, where it is approx. 3x faster moreover.
New records are:

Next < 10^80
CPU time: ca 24 hours.
