see http://list.seqfan.eu/pipermail/seqfan/2010-August/005856.html

this pops up unexpectedly in a study of the count of monomials in the Schur polynomials (generated by the partitions).
I can only verifiy correspondence up to n=8:   1, 2, 6, 22, 96, 492, 2952, 20588 .. combinatoricBoom...
and are aware of the trap of the SLSN (Strong Law of Small Numbers).

Can anyone help find a closed form, or more connections between A180389 and integer partitions?
