Introduction

Palindromic numbers are numbers which read the same from
 p_right left to right (forwards) as from the right to left (backwards) p_left
Here are a few random examples : 12921, 1960691, 389909983


Palindromic Sums of Powers of Consecutive Primes

[ May 27, 2001 ]
Hans Havermann, inspired by the topics of this page, programmed his 400 MHz iMac
using Mathematica 4 and got an impressive output after seven days of computation.
Palindromic Sums of Powers of Consecutive Primes
Here is his largest record
 510808567765808015 
which is the sum of the squares of the following 95 consecutive primes
733267332 + 733267692 + 733267872 + ... + 733283172 + 733283292 + 733283412


The exclusive Palindromic Prime number 373 can be expressed as a sequence of
Five Consecutive Primes in two ways :

373 = 67 + 71 + 73 + 79 + 83
373 = 32 + 52 + 72 + 112 + 132

Five Consecutive Primes starting from 7 are ideal candidates for creating two more palindromic numbers :

7 x 11 x 13 x 17 x 19 = 323323
72 + 112 + 132 + 172 + 192 = 989
