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).

Examples

			10601 is in the sequence, since 10601 = 10300 + 00301 and for no other k we have 10601 = k + reverse(k).
