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.
