Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{7}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - q^{2} + q^{4} + (\beta_{4} + \beta_1) q^{5} + (\beta_{2} - \beta_1) q^{7} - q^{8} + ( - \beta_{4} - \beta_1) q^{10} + (\beta_{5} + \beta_{4}) q^{11} + (\beta_{6} + 2) q^{13} + ( - \beta_{2} + \beta_1) q^{14}+ \cdots + (\beta_{7} - \beta_{6} + \beta_{3} + 2) q^{98}+O(q^{100}) \) Copy content Toggle raw display
