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.

\(f(q)\) \(=\) \( q - \beta_1 q^{2} + (\beta_{2} + \beta_1) q^{4} + ( - \beta_{2} - 2 \beta_1 + 2) q^{7} + ( - \beta_{2} - 1) q^{8} + (2 \beta_{2} + \beta_1 + 1) q^{11} + (3 \beta_{2} + 2) q^{13} + (2 \beta_{2} + \beta_1 + 3) q^{14}+ \cdots + (\beta_{2} - 2 \beta_1 + 1) q^{98}+O(q^{100}) \) Copy content Toggle raw display
