Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{5}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta_{4} + \beta_{3} - 1) q^{2} + ( - 2 \beta_{4} - \beta_{3} + 1) q^{4} + ( - \beta_{5} + \beta_{4} + \cdots + \beta_1) q^{5} + (2 \beta_{4} - \beta_{3} - 2) q^{8} + (\beta_{5} - \beta_{4} + \cdots + 2 \beta_{2}) q^{10}+ \cdots + ( - 7 \beta_{5} + 7 \beta_{4} + \cdots + \beta_1) q^{97}+O(q^{100}) \) Copy content Toggle raw display

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1323\mathbb{Z}\right)^\times\).
