Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = \sqrt{-10}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + 3 q^{2} + \beta q^{3} + 5 q^{4} + 3 \beta q^{6} + (2 \beta - 3) q^{7} + 3 q^{8} - q^{9} + 14 q^{11} + 5 \beta q^{12} - \beta q^{13} + (6 \beta - 9) q^{14} - 11 q^{16} - 2 \beta q^{17} - 3 q^{18} - 9 \beta q^{19} + \cdots - 14 q^{99} +O(q^{100}) \) 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.
