$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + \beta_{1} q^{3} + \beta_{2} q^{7} - q^{9} +O(q^{10})\) \( q + \beta_{1} q^{3} + \beta_{2} q^{7} - q^{9} -\beta_{3} q^{11} -2 \beta_{2} q^{17} + \beta_{3} q^{19} + \beta_{3} q^{21} + \beta_{2} q^{23} -4 \beta_{1} q^{27} -4 q^{31} -2 \beta_{2} q^{33} -6 \beta_{1} q^{37} + 3 \beta_{1} q^{43} -3 \beta_{2} q^{47} - q^{49} -2 \beta_{3} q^{51} -4 \beta_{1} q^{53} + 2 \beta_{2} q^{57} + 3 \beta_{3} q^{59} + \beta_{3} q^{61} -\beta_{2} q^{63} -3 \beta_{1} q^{67} + \beta_{3} q^{69} -12 q^{71} -2 \beta_{2} q^{73} -6 \beta_{1} q^{77} -4 q^{79} -5 q^{81} + 7 \beta_{1} q^{83} + 6 q^{89} -4 \beta_{1} q^{93} + 2 \beta_{2} q^{97} + \beta_{3} q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 4q - 4q^{9} + O(q^{10}) \) \( 4q - 4q^{9} - 16q^{31} - 4q^{49} - 48q^{71} - 16q^{79} - 20q^{81} + 24q^{89} + O(q^{100}) \)
