## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( 2 + i ) q^{5} -4 i q^{7} +O(q^{10})$$ $$q + ( 2 + i ) q^{5} -4 i q^{7} + 4 q^{11} + 4 i q^{13} -6 i q^{17} -4 q^{19} -4 i q^{23} + ( 3 + 4 i ) q^{25} + 4 q^{29} + ( 4 - 8 i ) q^{35} -4 i q^{37} + 8 q^{41} + 12 i q^{47} -9 q^{49} + 2 i q^{53} + ( 8 + 4 i ) q^{55} + 12 q^{59} + 2 q^{61} + ( -4 + 8 i ) q^{65} + 8 i q^{67} -8 q^{71} -16 i q^{73} -16 i q^{77} -8 q^{79} -8 i q^{83} + ( 6 - 12 i ) q^{85} + 16 q^{91} + ( -8 - 4 i ) q^{95} + 8 i q^{97} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q + 4q^{5} + O(q^{10})$$ $$2q + 4q^{5} + 8q^{11} - 8q^{19} + 6q^{25} + 8q^{29} + 8q^{35} + 16q^{41} - 18q^{49} + 16q^{55} + 24q^{59} + 4q^{61} - 8q^{65} - 16q^{71} - 16q^{79} + 12q^{85} + 32q^{91} - 16q^{95} + O(q^{100})$$
