start with a=48 and make the sum of the nontrivial divisors of a
(which is Chowa's function); you'll get b=75; iterate and you'll find a
again. What are the integers entering such loops?
I guess they are:
(not sure, though, that I forgot integers < 215)
I've searched by hand the table visible at A048050.
