%N A068065 Palindromes n for which there is a unique k such that n = k + reverse(k).
%C A068065 Subsequence of A068062; A068062(k) is in this sequence if and only if 
               A068064(k) = 1. At first sight, 121 seems to be missing, but in fact 
               121 does not belong here (cf. example in A068064).
%e A068065 10601 is in the sequence, since 10601 = 10300 + 00301 and for no other 
               k we have 10601 = k + reverse(k).
%Y A068065 Cf. A002113, A067030, A067032, A068062, A068064.
