$q$-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.

 $$f(q)$$ $$=$$ $$q + q^{3} -\beta q^{7} + q^{9} +O(q^{10})$$ $$q + q^{3} -\beta q^{7} + q^{9} + \beta q^{13} -\beta q^{21} + q^{25} + q^{27} + \beta q^{31} -\beta q^{37} + \beta q^{39} + q^{49} + \beta q^{61} -\beta q^{63} -2 q^{67} + q^{75} + \beta q^{79} + q^{81} -2 q^{91} + \beta q^{93} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 2q^{3} + 2q^{9} + O(q^{10})$$ $$2q + 2q^{3} + 2q^{9} + 2q^{25} + 2q^{27} + 2q^{49} - 4q^{67} + 2q^{75} + 2q^{81} - 4q^{91} + O(q^{100})$$
