Basis computation not working

ahorawa opened this issue · 0 comments

I tried to compute the basis of the space of modular forms for F = Q(sqrt(5)), level 7, weight [2,2]. I ran:

load "config.m";
F:=QuadraticField(5);
prec:=5;
M:=GradedRingOfHMFs(F, prec);
ZF:=Integers(F);
N:= Factorization(7*ZF)[1][1];
M2 := HMFSpace(M, N, [2,2]);
B2 := CuspFormBasis(M2);

and I got

CuspFormBasis(
Mk: Space of Hilbert modular forms over Quadratic Field with def...
)
NewCuspForms(
Mk: Space of Hilbert modular forms over Quadratic Field with def...
)
MagmaNewCuspForms(
Mk: Space of Hilbert modular forms over Quadratic Field with def...
)
