Comment (by zabrocki):
On two different macs am getting:
{{{
sage: s = SymmetricFunctions(QQ).s()
sage: p = SymmetricFunctions(QQ).p()
sage: sage: g = s(p([1]*47))
sage: g.coefficient([9,8,7,6,5,4,3,2,2,1])
14333651730948448927581696000
sage: sage: g = s(p([1]*47))
sage: g.coefficient([9,8,7,6,5,4,3,2,2,1])
6813423452539470910666189837844044800
}}}
The first time the value is computed it seems to be correct. The second
time it is random. This does not happen on linux.
