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.

\(f(q)\) \(=\) \( q + 2 q^{2} + (\beta_{2} + \beta_1 - 1) q^{3} + 4 q^{4} + (2 \beta_{2} + 2 \beta_1 - 2) q^{6} + 2 \beta_{3} q^{7} + 8 q^{8} + (2 \beta_{3} + 5 \beta_{2} - 2 \beta_1) q^{9} + ( - 4 \beta_{3} + 4 \beta_1) q^{11}+ \cdots + (20 \beta_{3} + 20 \beta_1 - 112) q^{99}+O(q^{100}) \) Copy content Toggle raw display
