%N Consider the Reverse and Add! problem (cf. A001127); of all the n-digit numbers N which eventually reach a palindrome, pick that number N which takes the greatest number of steps to converge (in case of a tie, pick the smallest N); sequence gives palindrome that is reached.
%C Since we do not even know if 196 eventually converges (see A006960, A023108) for n >= 3 these values are only conjectures.
