$q$-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.

\(f(q)\) \(=\) \( q + \beta_{2} q^{5} -\beta_{1} q^{7} +O(q^{10})\) \( q + \beta_{2} q^{5} -\beta_{1} q^{7} + \beta_{3} q^{11} -\beta_{1} q^{13} -\beta_{3} q^{17} -6 q^{19} -2 \beta_{2} q^{23} + 7 q^{25} -\beta_{2} q^{29} + \beta_{1} q^{31} -\beta_{3} q^{35} + 7 \beta_{1} q^{37} -\beta_{3} q^{41} -6 q^{43} -2 \beta_{2} q^{47} -5 q^{49} + \beta_{2} q^{53} + 12 \beta_{1} q^{55} + 2 \beta_{3} q^{59} + 5 \beta_{1} q^{61} -\beta_{3} q^{65} + 8 q^{67} -4 \beta_{2} q^{71} -12 q^{73} -2 \beta_{2} q^{77} -11 \beta_{1} q^{79} -3 \beta_{3} q^{83} -12 \beta_{1} q^{85} -2 \beta_{3} q^{89} + 2 q^{91} -6 \beta_{2} q^{95} +O(q^{100})\)
