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.

\(f(q)\) \(=\) \( q + (\beta_1 - 1) q^{3} - q^{5} + (\beta_{2} - \beta_1 - 1) q^{7} + (\beta_{2} - \beta_1 + 2) q^{9} - 2 \beta_1 q^{11} + (2 \beta_{2} + \beta_1 + 1) q^{13} + ( - \beta_1 + 1) q^{15} + (\beta_{2} + \beta_1 + 1) q^{17}+ \cdots + (4 \beta_{2} - 4 \beta_1 + 10) q^{99}+O(q^{100}) \) Copy content Toggle raw display
