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.

\(f(q)\) \(=\) \( q - 2 q^{2} - 3 q^{3} + 4 q^{4} + (\beta_1 - 2) q^{5} + 6 q^{6} + 7 q^{7} - 8 q^{8} + 9 q^{9} + ( - 2 \beta_1 + 4) q^{10} + (\beta_{2} - 5) q^{11} - 12 q^{12} + 13 q^{13} - 14 q^{14} + ( - 3 \beta_1 + 6) q^{15}+ \cdots + (9 \beta_{2} - 45) q^{99}+O(q^{100}) \) Copy content Toggle raw display
