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.

\(f(q)\) \(=\) \( q + ( - \beta_{2} - 1) q^{3} + (\beta_{4} - \beta_1 + 1) q^{5} + (\beta_{4} + \beta_{2} + \beta_1 + 1) q^{9} - q^{11} + ( - \beta_{3} + 2 \beta_1 + 1) q^{13} + ( - 2 \beta_{4} - \beta_{2} + \beta_1 - 2) q^{15}+ \cdots + ( - \beta_{4} - \beta_{2} - \beta_1 - 1) q^{99}+O(q^{100}) \) Copy content Toggle raw display
