$q$-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.

\(f(q)\) \(=\) \( q + \beta q^{3} + 5 q^{9} +O(q^{10})\) \( q + \beta q^{3} + 5 q^{9} + q^{11} + \beta q^{13} -\beta q^{17} + 2 \beta q^{19} -8 q^{23} -5 q^{25} + 2 \beta q^{27} + 2 q^{29} + 3 \beta q^{31} + \beta q^{33} + 2 q^{37} + 8 q^{39} -\beta q^{41} + 4 q^{43} + \beta q^{47} -8 q^{51} + 14 q^{53} + 16 q^{57} -3 \beta q^{59} + 3 \beta q^{61} -4 q^{67} -8 \beta q^{69} + 5 \beta q^{73} -5 \beta q^{75} + 16 q^{79} + q^{81} -6 \beta q^{83} + 2 \beta q^{87} + 4 \beta q^{89} + 24 q^{93} + 6 \beta q^{97} + 5 q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q + 10 q^{9} + O(q^{10}) \) \( 2 q + 10 q^{9} + 2 q^{11} - 16 q^{23} - 10 q^{25} + 4 q^{29} + 4 q^{37} + 16 q^{39} + 8 q^{43} - 16 q^{51} + 28 q^{53} + 32 q^{57} - 8 q^{67} + 32 q^{79} + 2 q^{81} + 48 q^{93} + 10 q^{99} + O(q^{100}) \)
