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.

\(f(q)\) \(=\) \( q + \beta_1 q^{2} + ( - \beta_{2} + 1) q^{3} + \beta_{2} q^{4} + 3 \beta_{3} q^{5} + ( - \beta_{3} + \beta_1) q^{6} + ( - 5 \beta_{3} + 5 \beta_1) q^{7} - 7 \beta_{3} q^{8} + 26 \beta_{2} q^{9} + (27 \beta_{2} - 27) q^{10}+ \cdots + 416 \beta_{3} q^{99}+O(q^{100}) \) Copy content Toggle raw display
