## $q$-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.

 $$f(q)$$ $$=$$ $$q + ( -2 + 2 i ) q^{3} -5 i q^{9} +O(q^{10})$$ $$q + ( -2 + 2 i ) q^{3} -5 i q^{9} + ( 2 + 2 i ) q^{11} -6 q^{17} + ( -6 + 6 i ) q^{19} -5 i q^{25} + ( 4 + 4 i ) q^{27} -8 q^{33} -6 i q^{41} + ( -6 - 6 i ) q^{43} + 7 q^{49} + ( 12 - 12 i ) q^{51} -24 i q^{57} + ( -10 - 10 i ) q^{59} + ( 6 - 6 i ) q^{67} -2 i q^{73} + ( 10 + 10 i ) q^{75} - q^{81} + ( 2 - 2 i ) q^{83} + 18 i q^{89} -10 q^{97} + ( 10 - 10 i ) q^{99} +O(q^{100})$$ $$\operatorname{Tr}(f)(q)$$ $$=$$ $$2q - 4q^{3} + O(q^{10})$$ $$2q - 4q^{3} + 4q^{11} - 12q^{17} - 12q^{19} + 8q^{27} - 16q^{33} - 12q^{43} + 14q^{49} + 24q^{51} - 20q^{59} + 12q^{67} + 20q^{75} - 2q^{81} + 4q^{83} - 20q^{97} + 20q^{99} + O(q^{100})$$
