Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{13}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q - \beta_1 q^{2} - 3 q^{3} + (\beta_{2} + 4) q^{4} + 3 \beta_1 q^{6} + ( - \beta_{8} - \beta_{5} - \beta_{3} + \cdots + 1) q^{7} + ( - \beta_{6} - 3 \beta_{3} - 3 \beta_1 - 3) q^{8} + 9 q^{9} + ( - \beta_{13} - 2 \beta_{9} + \cdots - 4) q^{11}+ \cdots + ( - 9 \beta_{13} - 18 \beta_{9} + \cdots - 36) q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 14 q - 42 q^{3} + 50 q^{4} + 27 q^{7} - 21 q^{8} + 126 q^{9} - 33 q^{11} - 150 q^{12} + 188 q^{13} - 287 q^{14} + 82 q^{16} + 146 q^{17} - 184 q^{19} - 81 q^{21} + 277 q^{22} + 164 q^{23} + 63 q^{24} + 103 q^{26}+ \cdots - 297 q^{99}+O(q^{100}) \) Copy content Toggle raw display
