$q$-expansion

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

\(f(q)\) \(=\) \( q + 2 \beta q^{5} +O(q^{10})\) \( q + 2 \beta q^{5} + 6 q^{11} + 4 \beta q^{13} + \beta q^{17} -3 \beta q^{19} + 4 q^{23} + 3 q^{25} + 6 q^{29} + 2 \beta q^{31} + 2 q^{37} -\beta q^{41} -10 q^{43} + 2 \beta q^{47} + 2 q^{53} + 12 \beta q^{55} -\beta q^{59} + 6 \beta q^{61} + 16 q^{65} -4 q^{67} -12 q^{71} + 7 \beta q^{73} + 4 q^{79} -\beta q^{83} + 4 q^{85} -3 \beta q^{89} -12 q^{95} -9 \beta q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q + 12q^{11} + 8q^{23} + 6q^{25} + 12q^{29} + 4q^{37} - 20q^{43} + 4q^{53} + 32q^{65} - 8q^{67} - 24q^{71} + 8q^{79} + 8q^{85} - 24q^{95} + O(q^{100}) \)
