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.

\(f(q)\) \(=\) \( q + q^{2} + ( - \beta_{2} + 1) q^{3} + q^{4} + ( - \beta_{2} + 1) q^{6} - \beta_1 q^{7} + q^{8} + ( - 3 \beta_{2} - 1) q^{9} + ( - 2 \beta_{3} - 4 \beta_1) q^{11} + ( - \beta_{2} + 1) q^{12} + ( - 3 \beta_{3} - 3 \beta_1) q^{13}+ \cdots + (14 \beta_{3} - 2 \beta_1) q^{99}+O(q^{100}) \) Copy content Toggle raw display
