Jun 18, 2016 at 17:59	comment	added	Will Chen		Why is it that the first invariant factor of the abelianization is in that set? For example, doesn't Aut(F2) act transitively on surjections to any finite cyclic group (or at least those of prime order?). I'm assuming that by {1,2,3,4,6} you mean that the first invariant factor is a cyclic group of order in that set?
