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

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