New description:
This ticket aims to extend capability of the class
ArithmeticSubgroup_Permutation in sage.modular.arithgroup_perm. This is
now possible to deal with any subgroup of `SL(2,Z)` and many new methods
are available (in particular equality of subgroups, conjugacy problem,
...)
I reimplement the method todd_coxeter of
sage.modular.arithgroup.arithgroup_generic to be faster and with more
output.
I also created a test file for arithmetic subgroup.
See details and documentation in the patch.
depends on #10334
