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.

\(f(q)\) \(=\) \( q - 2 \beta_{2} q^{2} + ( - 3 \beta_{2} + 3) q^{3} + (4 \beta_{2} - 4) q^{4} + (2 \beta_{2} + \beta_1) q^{5} - 6 q^{6} + 8 q^{8} - 9 \beta_{2} q^{9} + ( - 2 \beta_{3} - 4 \beta_{2} + \cdots + 6) q^{10}+ \cdots + (9 \beta_{3} + 297) q^{99}+O(q^{100}) \) Copy content Toggle raw display
