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

\(f(q)\) \(=\) \( q + 4 i q^{2} + 9 i q^{3} - 16 q^{4} - 36 q^{6} + 176 i q^{7} - 64 i q^{8} - 81 q^{9} - 60 q^{11} - 144 i q^{12} + 658 i q^{13} - 704 q^{14} + 256 q^{16} - 414 i q^{17} - 324 i q^{18} - 956 q^{19} - 1584 q^{21} + \cdots + 4860 q^{99} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/150\mathbb{Z}\right)^\times\).

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

Embeddings

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