Comment (by zabrocki):
The error seems to be within Symmetrica. I computed `s(p([1]*36))` and
stuck in a print statement to print out the intermediate symmetrica
object. I found that the coefficient of the partition `111122334567` is
`5.061293.630159.021056` and this agrees with what is returned by the
command `g = s(p([1]*36))`
{{{
sage: g.coefficient([7,6,5,4,3,3,2,2,1,1,1,1])
5061293630159021056
}}}
however the coefficient should be
{{{
sage: StandardTableaux([7,6,5,4,3,3,2,2,1,1,1,1]).cardinality()
12961662907729536000
}}}
