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.

\(f(q)\) \(=\) \( q + (\beta_1 + 3) q^{3} + (\beta_{2} - 7) q^{5} + (2 \beta_{2} + 2 \beta_1 - 4) q^{7} + (\beta_{2} + 2 \beta_1 + 30) q^{9} + ( - 2 \beta_{2} + 3 \beta_1 - 29) q^{11} + ( - \beta_{2} + 2 \beta_1 + 41) q^{13}+ \cdots + ( - 86 \beta_{2} - 18 \beta_1 - 812) q^{99}+O(q^{100}) \) Copy content Toggle raw display
