%N Lengths of k-cycles (k > 1) of permutation A113821 in order of their first appearance.

%C Sequence A115642 without repetition.

%e (16200,16301,16406,16515,16620,16733,16842) is the first 7-cycle of A113821, all of the twenty preceding cycles (cf. A115641) have length 4, 11, 3, 5, 16, 18, 66, 2, 24, 54, 165, 9 or 44 (thirteen different values), hence a(14) = 7.

%Y Cf. A113821, A115642, A115641.
