## $q$-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.

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