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.

\(f(q)\) \(=\) \( q + \beta_{2} q^{3} + ( - \beta_{3} - \beta_{2} + 5) q^{5} + ( - \beta_{3} + 3 \beta_{2} - \beta_1 - 1) q^{7} + ( - 5 \beta_{3} + 2 \beta_1 + 6) q^{9} + ( - \beta_{3} - 5 \beta_{2} - 5 \beta_1 + 9) q^{11}+ \cdots + ( - 60 \beta_{3} - 78 \beta_{2} + \cdots + 270) q^{99}+O(q^{100}) \) Copy content Toggle raw display
