%N Numbers in cycles of RATS sequences.
%C The set of all numbers in any cycle of RATS sequences, sorted into natural order.
%C This implies that for any value a(j) in this sequence, A036839(a(j)) is again member of the sequence.
%e The numbers 111, 222, 444, 888, 1677, 3489, 12333 and 44556 are in the sequence because they
%e are in the cycle shown in A066710. The numbers 117 and 288 are in the cycle demonstrated in A066711.
%e The numbers 4444, 8888, 16777, 34589, 112333, 444455, ..., 1112278888, 11999, 1119, 1223 are in the
%e cycle started at A161590(4). The numbers 11127 and 23388 are in the cycle started at A161590(7).
