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.

\(f(q)\) \(=\) \( q + (\beta_{2} + 2 \beta_1 + 2) q^{5} - 7 q^{7} + ( - 7 \beta_{2} - 3 \beta_1) q^{11} + (3 \beta_{2} - 8 \beta_1 - 2) q^{13} + (14 \beta_{2} + 22) q^{17} + ( - 14 \beta_{2} - 3 \beta_1 - 56) q^{19} + ( - 7 \beta_{2} + 11 \beta_1 + 112) q^{23}+ \cdots + (92 \beta_{2} + 142 \beta_1 - 838) q^{97}+O(q^{100}) \) Copy content Toggle raw display
