The number of partitions of n into parts not divisible by 3 with every part repeated at least twice seems to be the same as A132091

Expansion of psi(q^3)* chi(-q^9)/ f(-q^2) in powers of q where psi(), chi(), f() are Ramanujan theta functions.

which I have zero intuition for.

A b-file for the partition into n parts etc. is at http://home.att.net/~rhhardin/b132091.txt
n=1..902, if somebody wants to check higher terms on it.
