Sage can compute the genus of
,
,
and related curves. Here are some examples of the syntax:
sage: sage.modular.dims.g0(22) 2 sage: sage.modular.dims.g0(30) 3 sage: sage.modular.dims.g1(30) 9
See the code for
computing dimensions of spaces of modular forms
(in sage/modular/dims.py
) or the paper by
Oesterlé and Cohen [CO]
for some details.
