Comments

Permutation A094077 has fixed point 1, 2-cycle (2,3) and 5-cycle (14,23,16,27,19); there are no other finite cycles with terms < 500000. 4 is the smallest number that is not member of a known finite cycle of A094077.

Conjecture: Sequence is not periodic.

For the retrograde trajectory of 4 see A117150.
