## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( -2 - i ) q^{5} -i q^{7} +O(q^{10})$$ $$q + ( -2 - i ) q^{5} -i q^{7} -4 q^{11} + 2 i q^{13} + 2 i q^{17} + 2 q^{19} + 6 i q^{23} + ( 3 + 4 i ) q^{25} + 6 q^{29} + 6 q^{31} + ( -1 + 2 i ) q^{35} + 4 i q^{37} -4 i q^{43} + 4 i q^{47} - q^{49} + 2 i q^{53} + ( 8 + 4 i ) q^{55} + 4 q^{59} -2 q^{61} + ( 2 - 4 i ) q^{65} + 12 i q^{67} + 8 q^{71} + 14 i q^{73} + 4 i q^{77} -16 q^{79} -16 i q^{83} + ( 2 - 4 i ) q^{85} + 16 q^{89} + 2 q^{91} + ( -4 - 2 i ) q^{95} + 14 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2 q - 4 q^{5} + O(q^{10})$$ $$2 q - 4 q^{5} - 8 q^{11} + 4 q^{19} + 6 q^{25} + 12 q^{29} + 12 q^{31} - 2 q^{35} - 2 q^{49} + 16 q^{55} + 8 q^{59} - 4 q^{61} + 4 q^{65} + 16 q^{71} - 32 q^{79} + 4 q^{85} + 32 q^{89} + 4 q^{91} - 8 q^{95} + O(q^{100})$$
