Comment(by SimonKing):
I forgot one change w.r.t. your implementation: Division is not
implemented except for scalar divisors.
Continuing the example from above:
{{{
sage: p/X(3)
1/3*y2^3*x10 + 2/3*y3*x1
sage: p/p
NotImplementedError Traceback (most recent call
last)
...
NotImplementedError: Fraction Fields of Symmetric Polynomial Rings are not
implemented
}}}
Cheers,
Simon
