%N A088997 Base 10 numbers such that a(n) plus any positive palindrome less than 
               a(n) does not yield a palindrome.
%C A088997 This sequence can contain no palindromes since 0 is a palindrome and 
               any palindrome plus 0 is also a palindrome.
%e A088997 a(2) = 23 because 23 plus any previous positive palindromic number (0, 
               1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22) does not yield a palindrome.
