## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( -1 - 2 i ) q^{5} + i q^{7} +O(q^{10})$$ $$q + ( -1 - 2 i ) q^{5} + i q^{7} -4 i q^{13} -4 i q^{17} -4 q^{19} + 8 i q^{23} + ( -3 + 4 i ) q^{25} + 2 q^{29} -8 q^{31} + ( 2 - i ) q^{35} -8 i q^{37} -6 q^{41} -8 i q^{43} -8 i q^{47} - q^{49} -4 q^{59} -6 q^{61} + ( -8 + 4 i ) q^{65} + 8 i q^{67} -12 q^{71} + 4 i q^{73} + 4 q^{79} + ( -8 + 4 i ) q^{85} -10 q^{89} + 4 q^{91} + ( 4 + 8 i ) q^{95} -12 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 2q^{5} + O(q^{10})$$ $$2q - 2q^{5} - 8q^{19} - 6q^{25} + 4q^{29} - 16q^{31} + 4q^{35} - 12q^{41} - 2q^{49} - 8q^{59} - 12q^{61} - 16q^{65} - 24q^{71} + 8q^{79} - 16q^{85} - 20q^{89} + 8q^{91} + 8q^{95} + O(q^{100})$$
