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

\(f(q)\) \(=\) \( q + 2 i q^{2} + 2 i q^{3} - 4 q^{4} - 4 q^{6} + 7 i q^{7} - 8 i q^{8} + 23 q^{9} + 48 q^{11} - 8 i q^{12} - 56 i q^{13} - 14 q^{14} + 16 q^{16} - 114 i q^{17} + 46 i q^{18} - 2 q^{19} - 14 q^{21} + 96 i q^{22} + \cdots + 1104 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/350\mathbb{Z}\right)^\times\).

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

Embeddings

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