COMMENTS

Trajectory of n under map k > A111273(k) is periodic with period length 3.
n = A111273(A111273(A111273(n))), n <> A111273(A111273(n)), n <> A111273(n).
Apparently A111273 has infinitely many 3cycles.
The only kcycles with k > 3 and terms < 240000 are the 4cycles (84326,126489,149487,91992) and (94138,98417,135761,141207), the 6cycle (4,5,15,8,6,7), the 7cycle (16,17,51,34,35,30,31) and the 13cycle (28,29,87,58,59,118,119,68,46,47,94,95,48).

EXAMPLE

A111273(7494) = 18735, A111273(18735) = 9992 and A111273(9992) = 7494, hence
7494, 9992 and 18735 are in the sequence.
