%N A281369 Orbit of 25 under repeated applications of the map m -> A280864(m).
%C A281369 It is a strong conjecture that A280864 is a permutation of the positive integers. The orbit containing 25 appears to be the first infinite orbit. See A281370 for the orbit of 25 under the inverse permutation, and see A280864 for other orbits (there are several small cycles).
