$q$-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.

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