$q$-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.

 $$f(q)$$ $$=$$ $$q + \beta q^{5} -3 q^{9} +O(q^{10})$$ $$q + \beta q^{5} -3 q^{9} -\beta q^{13} -5 \beta q^{17} -3 q^{25} -4 q^{29} -12 q^{37} + 9 \beta q^{41} -3 \beta q^{45} -14 q^{53} + 11 \beta q^{61} -2 q^{65} -11 \beta q^{73} + 9 q^{81} -10 q^{85} + 3 \beta q^{89} + 5 \beta q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q - 6 q^{9} + O(q^{10})$$ $$2 q - 6 q^{9} - 6 q^{25} - 8 q^{29} - 24 q^{37} - 28 q^{53} - 4 q^{65} + 18 q^{81} - 20 q^{85} + O(q^{100})$$
