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.

\(f(q)\) \(=\) \( q + 2 q^{2} - 3 q^{3} + 4 q^{4} + ( - \beta_{2} + \beta_1 + 2) q^{5} - 6 q^{6} - 7 q^{7} + 8 q^{8} + 9 q^{9} + ( - 2 \beta_{2} + 2 \beta_1 + 4) q^{10} + ( - \beta_{2} + 3 \beta_1 - 16) q^{11} - 12 q^{12}+ \cdots + ( - 9 \beta_{2} + 27 \beta_1 - 144) q^{99}+O(q^{100}) \) Copy content Toggle raw display
