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.

\(f(q)\) \(=\) \( q - 4 q^{2} + ( - \beta_{2} + \beta_1 - 3) q^{3} + 16 q^{4} - 14 q^{5} + (4 \beta_{2} - 4 \beta_1 + 12) q^{6} + (9 \beta_{2} - 7 \beta_1 + 31) q^{7} - 64 q^{8} + (5 \beta_{2} - 20 \beta_1 + 66) q^{9} + 56 q^{10}+ \cdots + ( - 638 \beta_{2} - 4594 \beta_1 - 40998) q^{99}+O(q^{100}) \) Copy content Toggle raw display
