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.

\(f(q)\) \(=\) \( q + q^{2} + \beta_1 q^{3} + q^{4} - q^{5} + \beta_1 q^{6} + ( - \beta_{2} - \beta_1 + 1) q^{7} + q^{8} + (\beta_{2} - \beta_1 + 4) q^{9} - q^{10} + (2 \beta_{2} - \beta_1 + 2) q^{11} + \beta_1 q^{12}+ \cdots + (3 \beta_{2} - 3 \beta_1 + 21) q^{99}+O(q^{100}) \) Copy content Toggle raw display
