An all palindromic diophantine equation intermezzo

2423 = 26622 + 26622


[ May 23, 2002 ]
Jean Claude Rosa (email) intrigued by the above equation
went looking for other solutions of the form p3 = q2 + r2
(p, q and r palindromes). None were found for p from 11 up to 11611
but in the same spirit as WONplate 131 he found
an infinite amount of solutions ie. variations of the above equation.
[ 2(0)n4(0)n2 ]3 = [ 2(0)n6(0)n6(0)n2 ]2 + [ 2(0)n6(0)n6(0)n2 ]2

I (JCR) found also the following equation
3633 = 39932 + 39932 + 39932
and of course its infinite pattern partner !
[ 3(0)n6(0)n3 ]3 = 3 * [ 3(0)n9(0)n9(0)n3 ]2
