$q$-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.

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