Comment (by zabrocki):
The version you just posted seems to compile (I was having issues before)
but it looks like the fix only solves 1/2 of the problem.
{{{
sage: s = SymmetricFunctions(QQ).s()
sage: p = SymmetricFunctions(QQ).p()
sage: g = s(p([1]*36))
sage: g.coefficient([7,6,5,4,3,3,2,2,1,1,1,1])
12961662907729536000
sage: g = s(p([1]*47))
sage: s(p[2,2])
s[1, 1, 1, 1] - s[2, 1, 1] + 1589352607*s[2, 2] - s[3, 1] + s[4]
}}}
Are you getting similar results? We may have to go back to the drawing
board.
