## $q$-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.

 $$f(q)$$ $$=$$ $$q + 3 i q^{3} - 13 i q^{7} - 9 q^{9} +O(q^{10})$$ q + 3*i * q^3 - 13*i * q^7 - 9 * q^9 $$q + 3 i q^{3} - 13 i q^{7} - 9 q^{9} - 23 i q^{13} - 11 q^{19} + 39 q^{21} - 27 i q^{27} + 59 q^{31} + 26 i q^{37} + 69 q^{39} - 83 i q^{43} - 120 q^{49} - 33 i q^{57} - 121 q^{61} + 117 i q^{63} - 13 i q^{67} + 46 i q^{73} + 142 q^{79} + 81 q^{81} - 299 q^{91} + 177 i q^{93} + 167 i q^{97} +O(q^{100})$$ q + 3*i * q^3 - 13*i * q^7 - 9 * q^9 - 23*i * q^13 - 11 * q^19 + 39 * q^21 - 27*i * q^27 + 59 * q^31 + 26*i * q^37 + 69 * q^39 - 83*i * q^43 - 120 * q^49 - 33*i * q^57 - 121 * q^61 + 117*i * q^63 - 13*i * q^67 + 46*i * q^73 + 142 * q^79 + 81 * q^81 - 299 * q^91 + 177*i * q^93 + 167*i * q^97 $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q - 18 q^{9}+O(q^{10})$$ 2 * q - 18 * q^9 $$2 q - 18 q^{9} - 22 q^{19} + 78 q^{21} + 118 q^{31} + 138 q^{39} - 240 q^{49} - 242 q^{61} + 284 q^{79} + 162 q^{81} - 598 q^{91}+O(q^{100})$$ 2 * q - 18 * q^9 - 22 * q^19 + 78 * q^21 + 118 * q^31 + 138 * q^39 - 240 * q^49 - 242 * q^61 + 284 * q^79 + 162 * q^81 - 598 * q^91

## Character values

We give the values of $$\chi$$ on generators for $$\left(\mathbb{Z}/300\mathbb{Z}\right)^\times$$.

 $$n$$ $$101$$ $$151$$ $$277$$ $$\chi(n)$$ $$-1$$ $$1$$ $$-1$$

## Embeddings

For each embedding $$\iota_m$$ of the coefficient field, the values $$\iota_m(a_n)$$ are shown below.
