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 : 535, 3773, 246191642


A nice coincidence occurred with Four Consecutive Integers

59 + 60 + 61 + 62 = 242
593 + 603 + 613 + 623 = 886688



Sources Revealed

Huen Y.K. from Singapore developed a general generating function for palindromic sums and products
of consecutive integers using concise programcode written for Macsyma 2.2.1.
