%N A015993 Twelve iterations of Reverse and Add are needed to reach a palindrome.
%C A015993 The number of iterations starts at 1, so palindromes (cf. A002113) are 
               not excluded. This sequence coincides with the corresponding sequence 
               excluding palindromes (A065217) for the entries shown in the database. 
               The first divergence occurs at 10901.
