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.

\(f(q)\) \(=\) \( q - 3 q^{3} + ( - \beta_1 + 2) q^{5} - 7 q^{7} + 9 q^{9} + (\beta_{2} - \beta_1 - 16) q^{11} + ( - \beta_{2} - 4 \beta_1 + 2) q^{13} + (3 \beta_1 - 6) q^{15} + (\beta_{2} - \beta_1 + 18) q^{17} + ( - \beta_{2} - 2 \beta_1 - 28) q^{19}+ \cdots + (9 \beta_{2} - 9 \beta_1 - 144) q^{99}+O(q^{100}) \) Copy content Toggle raw display
