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.

\(f(q)\) \(=\) \( q - \beta_{2} q^{3} - q^{5} - \beta_1 q^{7} + ( - 2 \beta_{2} + \beta_1 + 1) q^{9} - 2 \beta_1 q^{11} + (\beta_{2} + 2 \beta_1 - 2) q^{13} + \beta_{2} q^{15} + (\beta_1 - 2) q^{17} + 2 \beta_{2} q^{19}+ \cdots + (2 \beta_{2} + 2 \beta_1 - 8) q^{99}+O(q^{100}) \) Copy content Toggle raw display
