Comment(by Niels):
I believe the formulas used here are incorrect. I'm not sure, but they
appear similar to the erroneous formula's from Cohen's book. I'm currently
working on an implementation that uses different formulas. I expect that
to be done within two weeks.
One of my colleagues is working on y^2^ = quartic, which I will implement
for him. I expect this to be done within a couple of weeks. During Sage
Days 23 plans were made for other curves too, but I'm not sure anyone is
working on those.
