Comment (by zabrocki):
There is a function `test_integer` in the symmetrica package. It passes
on some integers, but not all!
{{{
sage: from sage.libs.symmetrica.symmetrica import test_integer
sage: s = SymmetricFunctions(QQ).s()
sage: p = SymmetricFunctions(QQ).p()
sage: g = s(p([1]*35))
sage: all( test_integer(c)==c for c in g.coefficients())
True
sage: g = s(p([1]*36))
sage: all( test_integer(c)==c for c in g.coefficients())
False
sage: c=StandardTableaux([10,9,8,7,6,5,4,3,2,1]).cardinality()
sage: test_integer(c)==c
False
}}}
