Palindromic Number
A symmetrical number which is written in some base 
as 
. The first few are 0, 1, 2, 3, 4,5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, ... (Sloane's A002113).
The first few 
for which the Pronic Number 
is palindromic are 1, 2, 16, 77, 538, 1621, ... (Sloane's A028336),and the first few palindromic numbers which are Pronic are 2, 6, 272, 6006, 289982, ...(Sloane's A028337). The first few numbers whose squares are palindromic are 1, 2, 3, 11, 22, 26, ... (Sloane's A002778), and thefirst few palindromic squares are 1, 4, 9, 121, 484, 676, ... (Sloane's A002779).
