Regarding some seqs about various sums over divisors:
A000203 (all divs)
A000593 (odd divs)
A048250 (square-free divs)
A034448 (unitary divs)
A048146 (non-unitary divs)
A162296 (square-full divs)
Are any of the formulas (given at p.347-348 of the fxtbook) connecting
these to certain generating for integer partitions functions new?
(fxtbook URL is http://www.jjj.de/fxt/#fxtbook ).
I am asking because I never toyed around with sum-of-divs functions.
