## $q$-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.

 $$f(q)$$ $$=$$ $$q + \beta q^{3} + \beta q^{5} - q^{7} + q^{9} +O(q^{10})$$ $$q + \beta q^{3} + \beta q^{5} - q^{7} + q^{9} + 2 \beta q^{11} + 3 \beta q^{13} -2 q^{15} -6 q^{17} -3 \beta q^{19} -\beta q^{21} + 6 q^{23} + 3 q^{25} + 4 \beta q^{27} -2 \beta q^{29} + 4 q^{31} -4 q^{33} -\beta q^{35} -6 \beta q^{37} -6 q^{39} + 6 q^{41} -6 \beta q^{43} + \beta q^{45} + q^{49} -6 \beta q^{51} + 4 \beta q^{53} -4 q^{55} + 6 q^{57} -\beta q^{59} -9 \beta q^{61} - q^{63} -6 q^{65} + 6 \beta q^{69} + 2 q^{73} + 3 \beta q^{75} -2 \beta q^{77} -8 q^{79} -5 q^{81} + 11 \beta q^{83} -6 \beta q^{85} + 4 q^{87} + 6 q^{89} -3 \beta q^{91} + 4 \beta q^{93} + 6 q^{95} -10 q^{97} + 2 \beta q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{7} + 2q^{9} + O(q^{10})$$ $$2q - 2q^{7} + 2q^{9} - 4q^{15} - 12q^{17} + 12q^{23} + 6q^{25} + 8q^{31} - 8q^{33} - 12q^{39} + 12q^{41} + 2q^{49} - 8q^{55} + 12q^{57} - 2q^{63} - 12q^{65} + 4q^{73} - 16q^{79} - 10q^{81} + 8q^{87} + 12q^{89} + 12q^{95} - 20q^{97} + O(q^{100})$$
