Comment:
This looks good with one exception: we (still) can't have the action of Tn
with n not squarefree:
{{{
sage: CuspForms(Gamma1(22), 2).new_submodule().hecke_matrix(9)
...
NotImplementedError: either character or _compute_hecke_matrix_prime_power
must be overloaded in a derived class
}}}
Do you want to try to fix this here as well, or put this into a new
ticket?
