Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{17}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \beta_{3} q^{3} + \beta_{11} q^{5} - \beta_{7} q^{7} + ( - \beta_{2} + 1) q^{9} + ( - \beta_{17} + \beta_{16} + \cdots - \beta_{13}) q^{11} + (\beta_{13} + \beta_{12} - \beta_{10} + \cdots - 1) q^{13}+ \cdots + (\beta_{17} + 3 \beta_{15} + \beta_{14} + \cdots + 2) q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 18 q - 2 q^{3} + q^{7} + 12 q^{9} - 4 q^{13} + 6 q^{15} - 10 q^{17} - 7 q^{21} - 6 q^{23} + 5 q^{25} - 20 q^{27} + 2 q^{29} + 9 q^{31} + 3 q^{35} + 18 q^{37} + 11 q^{39} - 9 q^{41} - 14 q^{43} + 30 q^{45}+ \cdots - 18 q^{97}+O(q^{100}) \) Copy content Toggle raw display
