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.

\(f(q)\) \(=\) \( q + \beta_{5} q^{2} - \beta_{3} q^{4} + \beta_1 q^{7} - \beta_1 q^{8} + (\beta_{5} - 2 \beta_{3} - \beta_1) q^{11} + (\beta_{6} + \beta_{5} - \beta_{4} + \cdots - 1) q^{13} + q^{14} - q^{16} + ( - \beta_{7} + \beta_{6} + \cdots - \beta_{4}) q^{17}+ \cdots + \beta_1 q^{98}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 8 q - 8 q^{13} + 8 q^{14} - 8 q^{16} - 8 q^{22} - 16 q^{23} + 16 q^{37} - 8 q^{38} + 8 q^{43} - 16 q^{44} + 8 q^{46} + 8 q^{47} + 8 q^{52} - 32 q^{53} + 8 q^{58} + 8 q^{59} - 32 q^{61} - 32 q^{62} - 16 q^{67}+ \cdots - 16 q^{97}+O(q^{100}) \) Copy content Toggle raw display
