-expansion
comment: q-expansion
sage: f.q_expansion() # note that sage often uses an isomorphic number field
gp: mfcoefs(f, 20)
Coefficients of the -expansion are expressed in terms of a primitive root of unity . We also show the integral -expansion of the trace form.
Character values
We give the values of on generators for .
