Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{5}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_1 q^{2} + ( - \beta_{5} - \beta_1) q^{3} + (\beta_{2} - 1) q^{4} + ( - \beta_{4} - \beta_{2} - 3) q^{6} + (3 \beta_{5} - \beta_{3} + \beta_1) q^{7} + (2 \beta_{3} - 3 \beta_1) q^{8} + (3 \beta_{4} - 3 \beta_{2} + 4) q^{9}+ \cdots + ( - 33 \beta_{4} + 33 \beta_{2} - 44) q^{99}+O(q^{100}) \) Copy content Toggle raw display
