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.

\(f(q)\) \(=\) \( q + (\beta_{5} + \beta_1 - 1) q^{2} + ( - \beta_{4} - \beta_{2}) q^{3} + ( - 2 \beta_{5} + 2 \beta_{4} + \cdots - \beta_1) q^{4} + (\beta_{4} + 1) q^{5} + (2 \beta_{5} - \beta_{4} - 2 \beta_{3} + \cdots - 2) q^{6}+ \cdots + ( - 3 \beta_{5} - 3 \beta_{4} + 3) q^{99}+O(q^{100}) \) Copy content Toggle raw display
