## $q$-expansion

comment: q-expansion

sage: f.q_expansion() # note that sage often uses an isomorphic number field

gp: mfcoefs(f, 20)

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + i q^{7}+O(q^{10})$$ q + i * q^7 $$q + i q^{7} + 6 q^{11} - 5 i q^{13} + 6 i q^{17} + 5 q^{19} + 6 i q^{23} - 6 q^{29} + q^{31} + 2 i q^{37} - i q^{43} + 6 i q^{47} + 6 q^{49} - 12 i q^{53} + 6 q^{59} - 13 q^{61} - 11 i q^{67} - 2 i q^{73} + 6 i q^{77} + 8 q^{79} + 6 i q^{83} + 5 q^{91} - 7 i q^{97} +O(q^{100})$$ q + i * q^7 + 6 * q^11 - 5*i * q^13 + 6*i * q^17 + 5 * q^19 + 6*i * q^23 - 6 * q^29 + q^31 + 2*i * q^37 - i * q^43 + 6*i * q^47 + 6 * q^49 - 12*i * q^53 + 6 * q^59 - 13 * q^61 - 11*i * q^67 - 2*i * q^73 + 6*i * q^77 + 8 * q^79 + 6*i * q^83 + 5 * q^91 - 7*i * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q+O(q^{10})$$ 2 * q $$2 q + 12 q^{11} + 10 q^{19} - 12 q^{29} + 2 q^{31} + 12 q^{49} + 12 q^{59} - 26 q^{61} + 16 q^{79} + 10 q^{91}+O(q^{100})$$ 2 * q + 12 * q^11 + 10 * q^19 - 12 * q^29 + 2 * q^31 + 12 * q^49 + 12 * q^59 - 26 * q^61 + 16 * q^79 + 10 * q^91

## Character values
