Hi:

I'm wondering if the analog of the following Magma commands
exist in Sage yet:

ClassicalModularPolynomial, CanonicalModularPolynomial,
AtkinModularPolynomial.

The modular polynomil $H_N$ has the property that
$H_N(x,y)= 0$ describes (an affine patch of) $X_0(N)$.
(I'm trying to remove all mention of Magma from a paper
I wrote long ago http://arxiv.org/abs/math.NT/0403548
and this question arose from that.)

Thanks,
David JOyner
