Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{11}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_{2} q^{3} - \beta_{5} q^{5} - \beta_{7} q^{7} + (\beta_{4} + 4) q^{9} + (\beta_{10} + \beta_{9} - \beta_{2}) q^{11} - 13 q^{13} + ( - \beta_{10} - 2 \beta_{8} + \cdots + \beta_{2}) q^{15} + (2 \beta_{5} + \beta_{4} - \beta_{3} - 1) q^{17}+ \cdots + ( - 3 \beta_{10} - 15 \beta_{9} + \cdots - 9 \beta_{2}) q^{99}+O(q^{100}) \) Copy content Toggle raw display
\(\operatorname{Tr}(f)(q)\) \(=\) \( 12 q + 54 q^{9} - 156 q^{13} - 54 q^{21} - 408 q^{25} - 360 q^{33} + 636 q^{37} - 810 q^{45} + 336 q^{49} - 1260 q^{57} + 960 q^{61} - 252 q^{69} + 3216 q^{73} - 2538 q^{81} + 2196 q^{85} - 1116 q^{93}+ \cdots + 4800 q^{97}+O(q^{100}) \) Copy content Toggle raw display
