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.

\(f(q)\) \(=\) \( q + (\beta_1 - 1) q^{2} + (\beta_{2} + 3) q^{4} + \beta_{2} q^{5} + q^{7} + ( - 2 \beta_{2} + \beta_1 - 3) q^{8} + ( - 2 \beta_{2} - 2) q^{10} + ( - \beta_{2} + \beta_1 + 2) q^{13} + (\beta_1 - 1) q^{14}+ \cdots + (\beta_1 - 1) q^{98}+O(q^{100}) \) Copy content Toggle raw display
