$q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$\beta = 2\sqrt{5}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + q^{5} -\beta q^{7} +O(q^{10})$$ $$q + q^{5} -\beta q^{7} + \beta q^{11} + 4 q^{13} + 2 q^{17} -2 \beta q^{23} + q^{25} -6 q^{29} + 2 \beta q^{31} -\beta q^{35} + 8 q^{37} + 8 q^{41} + 2 \beta q^{47} + 13 q^{49} -6 q^{53} + \beta q^{55} + \beta q^{59} + 10 q^{61} + 4 q^{65} + 2 \beta q^{67} + 2 \beta q^{71} + 6 q^{73} -20 q^{77} -2 \beta q^{79} -2 \beta q^{83} + 2 q^{85} + 4 q^{89} -4 \beta q^{91} + 2 q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 2q^{5} + O(q^{10})$$ $$2q + 2q^{5} + 8q^{13} + 4q^{17} + 2q^{25} - 12q^{29} + 16q^{37} + 16q^{41} + 26q^{49} - 12q^{53} + 20q^{61} + 8q^{65} + 12q^{73} - 40q^{77} + 4q^{85} + 8q^{89} + 4q^{97} + O(q^{100})$$
