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.

\(f(q)\) \(=\) \( q + ( - \beta_{2} + \beta_1) q^{2} + ( - 4 \beta_{2} + \beta_1) q^{3} + (2 \beta_{3} + 4) q^{4} + (5 \beta_{3} - 13) q^{6} + (4 \beta_{2} + 10 \beta_1) q^{7} + ( - 10 \beta_{2} + 6 \beta_1) q^{8} + (8 \beta_{3} - 22) q^{9}+ \cdots + ( - 88 \beta_{3} + 242) q^{99}+O(q^{100}) \) Copy content Toggle raw display
