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

\(f(q)\) \(=\) \( q + \beta_1 q^{2} + (\beta_{2} + 2) q^{4} + ( - \beta_{2} + \beta_1 - 2) q^{7} + (\beta_{2} + \beta_1) q^{8} + \beta_{2} q^{11} - 5 q^{13} + ( - 3 \beta_1 + 4) q^{14} + \beta_1 q^{16} + ( - 2 \beta_{2} - \beta_1 + 2) q^{17}+ \cdots + ( - 4 \beta_{2} + 6 \beta_1 - 20) q^{98}+O(q^{100}) \) Copy content Toggle raw display
