$q$-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.

 $$f(q)$$ $$=$$ $$q - q^{5} -\beta q^{7} +O(q^{10})$$ $$q - q^{5} -\beta q^{7} - q^{11} - q^{13} - q^{17} - q^{19} + q^{23} -\beta q^{31} + \beta q^{35} + \beta q^{37} - q^{41} + q^{43} -\beta q^{47} - q^{49} -\beta q^{53} + q^{55} -\beta q^{61} + q^{65} + \beta q^{73} + \beta q^{77} -\beta q^{83} + q^{85} + \beta q^{89} + \beta q^{91} + q^{95} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{5} + O(q^{10})$$ $$2q - 2q^{5} - 2q^{11} - 2q^{13} - 2q^{17} - 2q^{19} + 2q^{23} - 2q^{41} + 2q^{43} - 2q^{49} + 2q^{55} + 2q^{65} + 2q^{85} + 2q^{95} + O(q^{100})$$
