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.

\(f(q)\) \(=\) \( q - 3 \beta_{2} q^{2} + (\beta_{2} - \beta_1) q^{3} - q^{4} + ( - 3 \beta_{3} + 6) q^{6} + ( - 2 \beta_{2} - 5 \beta_1) q^{7} - 21 \beta_{2} q^{8} + (3 \beta_{3} - 4) q^{9} + (5 \beta_{3} - 16) q^{11}+ \cdots + ( - 53 \beta_{3} + 469) q^{99}+O(q^{100}) \) Copy content Toggle raw display
