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.

\(f(q)\) \(=\) \( q - \beta_1 q^{5} + (\beta_1 - 1) q^{7} - q^{11} + ( - \beta_{2} - 1) q^{13} + ( - \beta_1 + 2) q^{17} + (\beta_1 - 1) q^{19} + (\beta_{2} - \beta_1) q^{23} + (\beta_{2} - \beta_1 + 5) q^{25} + ( - \beta_{2} + 2) q^{29}+ \cdots + ( - 2 \beta_{2} + 2 \beta_1 - 1) q^{97}+O(q^{100}) \) Copy content Toggle raw display
