Comment (by vbraun):
Thats really a pattern that is all over the combinatorics stuff:
{{{
sage: iter(Partitions(4)).next()[0]
4
sage: type(_)
<type 'int'>
}}}
or
{{{
sage: g = SymmetricGroup(3).gen(0)
sage: type(g(1))
<type 'int'>
}}}
I've tripped more than once over this, its really common to want to do
`n.factorial()` for some integer from a partition.
