## $q$-expansion

Coefficients of the $$q$$-expansion are expressed in terms of $$i = \sqrt{-1}$$. We also show the integral $$q$$-expansion of the trace form.

 $$f(q)$$ $$=$$ $$q + i q^{3} -i q^{7} - q^{9} +O(q^{10})$$ $$q + i q^{3} -i q^{7} - q^{9} -3 q^{11} -4 i q^{13} + 6 i q^{17} + 4 q^{19} + q^{21} + 3 i q^{23} -i q^{27} -3 q^{29} -10 q^{31} -3 i q^{33} + 7 i q^{37} + 4 q^{39} -i q^{43} + 12 i q^{47} - q^{49} -6 q^{51} + 6 i q^{53} + 4 i q^{57} -12 q^{59} -4 q^{61} + i q^{63} + 7 i q^{67} -3 q^{69} + 9 q^{71} + 2 i q^{73} + 3 i q^{77} -17 q^{79} + q^{81} -6 i q^{83} -3 i q^{87} -4 q^{91} -10 i q^{93} -2 i q^{97} + 3 q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{9} + O(q^{10})$$ $$2q - 2q^{9} - 6q^{11} + 8q^{19} + 2q^{21} - 6q^{29} - 20q^{31} + 8q^{39} - 2q^{49} - 12q^{51} - 24q^{59} - 8q^{61} - 6q^{69} + 18q^{71} - 34q^{79} + 2q^{81} - 8q^{91} + 6q^{99} + O(q^{100})$$
