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

\(f(q)\) \(=\) \( q + i q^{3} + 7 i q^{7} + 26 q^{9} - 7 q^{11} - 23 i q^{13} + 25 i q^{17} + 62 q^{19} - 7 q^{21} - 86 i q^{23} + 53 i q^{27} + 29 q^{29} - 12 q^{31} - 7 i q^{33} + 150 i q^{37} + 23 q^{39} + 204 q^{41} + \cdots - 182 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/700\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(351\) \(477\)
\(\chi(n)\) \(1\) \(1\) \(-1\)

Embeddings
