%N Numbers found in the cycles of the iterated sum of deficient divisors function.
%C The 1-cycles (or fixed points) greater than 1 are given in A125310, the 3-cycle terms are given in A274339, the 4-cycle terms are given in A274340 and A274380, and the 10-cycle terms are given in A274338. This sequence was suggested to me by _Michel Marcus_ when I was submitting the 3-cycle, 4-cycle, and 10-cycle sequences.
%Y Cf. A125310, A187793, A274338, A274339, A274340, A274380.
