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.

\(f(q)\) \(=\) \( q + ( - \beta_{2} - 1) q^{2} + 9 q^{3} + ( - 4 \beta_1 - 8) q^{4} + ( - 9 \beta_{2} - 9) q^{6} + (7 \beta_{2} + 31 \beta_1 - 38) q^{7} + (28 \beta_{2} + 8 \beta_1 + 20) q^{8} + 81 q^{9} - 121 q^{11} + ( - 36 \beta_1 - 72) q^{12}+ \cdots - 9801 q^{99}+O(q^{100}) \) Copy content Toggle raw display
