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.

\(f(q)\) \(=\) \( q + ( - 2 \beta_1 - 2) q^{2} + 8 \beta_1 q^{4} + (7 \beta_{3} + 7 \beta_{2} + 7 \beta_1 + 7) q^{7} + ( - 16 \beta_1 + 16) q^{8} + (7 \beta_{3} - 116) q^{11} + ( - 19 \beta_{3} + 19 \beta_{2} + \cdots + 84) q^{13}+ \cdots + (392 \beta_{3} - 392 \beta_{2} + \cdots + 5978) q^{98}+O(q^{100}) \) Copy content Toggle raw display
