Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3,\beta_4\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \beta_1 q^{3} + q^{5} + (\beta_{3} - \beta_{2}) q^{7} + (\beta_{2} + 2) q^{9} + (\beta_{3} - 1) q^{11} + ( - \beta_{3} - \beta_1 + 3) q^{13} - \beta_1 q^{15} + (\beta_{4} + 1) q^{17} + ( - \beta_{4} - \beta_{2}) q^{19}+ \cdots + (3 \beta_{3} + 2 \beta_1 + 1) q^{99}+O(q^{100}) \) Copy content Toggle raw display
