Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

COMMENTS
Iterating the map x -> A098189(x) may enter a cycle with 53 members
(and there may be distinct cycles each with 53 members). The sequence
lists all starting values of x such that (after some transient x) one of these cycles of length 53 is entered.
FORMULA
{x: A098190(x) = 53}.
EXAMPLE
None of the values of A098192, A098193 or A098195 is in the sequence, because these will enter or are already in cycles of length 29 or 7.
