$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of \(\beta = 2\sqrt{2}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + 2 \beta q^{5} + 2 \beta q^{7} +O(q^{10})\) \( q + 2 \beta q^{5} + 2 \beta q^{7} + 4 q^{11} + 4 \beta q^{13} + 2 q^{17} -4 q^{19} + 4 \beta q^{23} + 3 q^{25} -2 \beta q^{29} -6 \beta q^{31} + 8 q^{35} + 10 q^{41} -12 q^{43} -4 \beta q^{47} + q^{49} -2 \beta q^{53} + 8 \beta q^{55} -4 q^{59} -8 \beta q^{61} + 16 q^{65} -4 q^{67} -4 \beta q^{71} + 2 q^{73} + 8 \beta q^{77} -6 \beta q^{79} -4 q^{83} + 4 \beta q^{85} + 6 q^{89} + 16 q^{91} -8 \beta q^{95} + 14 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q + 8q^{11} + 4q^{17} - 8q^{19} + 6q^{25} + 16q^{35} + 20q^{41} - 24q^{43} + 2q^{49} - 8q^{59} + 32q^{65} - 8q^{67} + 4q^{73} - 8q^{83} + 12q^{89} + 32q^{91} + 28q^{97} + O(q^{100}) \)
