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.

\(f(q)\) \(=\) \( q + \beta_1 q^{2} + (\beta_{3} - 71) q^{4} + (32 \beta_{2} + 16 \beta_1) q^{7} + (51 \beta_{2} - 39 \beta_1) q^{8} + (32 \beta_{3} - 140) q^{11} + (223 \beta_{2} + 16 \beta_1) q^{13} + ( - 48 \beta_{3} - 1584) q^{14}+ \cdots + ( - 91392 \beta_{2} - 11609 \beta_1) q^{98}+O(q^{100}) \) Copy content Toggle raw display
