Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3,\beta_4\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{2} - \beta_{2} q^{3} + q^{4} + (\beta_1 + 1) q^{5} + \beta_{2} q^{6} + ( - \beta_{3} - 2) q^{7} - q^{8} + (\beta_{4} - \beta_{2} - \beta_1) q^{9} + ( - \beta_1 - 1) q^{10} - \beta_{2} q^{12}+ \cdots + (\beta_{4} - 2 \beta_{3} + \beta_{2} - 1) q^{98}+O(q^{100}) \) Copy content Toggle raw display
