[seqfan] Re: Symmetric group S_n as product of at most A225788(n) cyclic subgroups

[Richard J. Mathar]

On step back concerning http://list.seqfan.eu/pipermail/seqfan/2013-May/011206.html :

Which of the nonisomorphic Abelian subgroups of S_n are counted
in A023893 but not in A009490? (Does A009490 count only
nonisomorphic subgroups of different order, or does the g.f. mean
that the group of order 1 is overcounted? )
The titles suggest that the sequences are the same, but they
obviously are not.
