Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3,\beta_4\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + (\beta_{4} + \beta_{2}) q^{2} + ( - \beta_{4} + \beta_{3} + 2 \beta_1) q^{4} + ( - \beta_{3} + 2 \beta_{2} + 2) q^{5} + ( - \beta_{4} - \beta_{3} + \beta_{2} + \cdots + 1) q^{7} + (\beta_{4} + \beta_{3} + \beta_{2} + 2) q^{8}+ \cdots + ( - 2 \beta_{4} + 3 \beta_{3} + \cdots - 5) q^{98}+O(q^{100}) \) Copy content Toggle raw display
