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

The sequence for parameter 'A' is 2, 3, 4, 5, ... [+ 1]
The 'B' CUDApalin parameters are given by A046092 → 4 times triangular numbers: a(n) = 2*n*(n+1).
The 'C' CUDApalin parameters are given by A002492 → Sum of the first n even squares: 2*n*(n+1)*(2*n+1)/3.
