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

\(f(q)\) \(=\) \( q + 10 i q^{2} - 14 i q^{3} - 68 q^{4} + 140 q^{6} + 49 i q^{7} - 360 i q^{8} + 47 q^{9} + 232 q^{11} + 952 i q^{12} - 140 i q^{13} - 490 q^{14} + 1424 q^{16} + 1722 i q^{17} + 470 i q^{18} + 98 q^{19} + \cdots + 10904 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/175\mathbb{Z}\right)^\times\).

\(n\) \(101\) \(127\)
\(\chi(n)\) \(1\) \(-1\)

Embeddings

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