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.

\(f(q)\) \(=\) \( q - \beta_{2} q^{5} + ( - \beta_{2} - \beta_1) q^{7} + 3 q^{11} + (2 \beta_1 + 1) q^{13} - \beta_1 q^{17} + ( - \beta_{2} + \beta_1 - 1) q^{19} + (\beta_{2} + \beta_1 + 1) q^{23} + ( - \beta_{2} - 2 \beta_1 + 1) q^{25}+ \cdots + ( - \beta_{2} + 6 \beta_1 + 2) q^{97}+O(q^{100}) \) Copy content Toggle raw display
