Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 2i\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + 11 \beta q^{5}+O(q^{10}) \) Copy content Toggle raw display \( q + 11 \beta q^{5} + 46 \beta q^{13} - 104 q^{17} - 359 q^{25} - 65 \beta q^{29} + 198 \beta q^{37} + 472 q^{41} - 343 q^{49} - 259 \beta q^{53} + 234 \beta q^{61} - 2024 q^{65} + 1098 q^{73} - 1144 \beta q^{85} + 176 q^{89} + 594 q^{97} +O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1152\mathbb{Z}\right)^\times\).

\(n\) \(127\) \(641\) \(901\)
\(\chi(n)\) \(1\) \(1\) \(-1\)

Embeddings

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