$q$-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.

\(f(q)\) \(=\) \( q + ( -1 - i ) q^{3} + ( 1 - i ) q^{7} -i q^{9} +O(q^{10})\) \( q + ( -1 - i ) q^{3} + ( 1 - i ) q^{7} -i q^{9} + 4 i q^{11} + ( -4 + 4 i ) q^{13} + ( -4 - 4 i ) q^{17} + 4 q^{19} -2 q^{21} + ( 5 + 5 i ) q^{23} + ( -4 + 4 i ) q^{27} + 2 i q^{29} + 8 i q^{31} + ( 4 - 4 i ) q^{33} + 8 q^{39} -4 q^{41} + ( -7 - 7 i ) q^{43} + ( 3 - 3 i ) q^{47} + 5 i q^{49} + 8 i q^{51} + ( -4 + 4 i ) q^{53} + ( -4 - 4 i ) q^{57} + 4 q^{59} + 8 q^{61} + ( -1 - i ) q^{63} + ( 3 - 3 i ) q^{67} -10 i q^{69} + 16 i q^{71} + ( 4 - 4 i ) q^{73} + ( 4 + 4 i ) q^{77} + 8 q^{79} + 5 q^{81} + ( 5 + 5 i ) q^{83} + ( 2 - 2 i ) q^{87} -10 i q^{89} + 8 i q^{91} + ( 8 - 8 i ) q^{93} + ( 12 + 12 i ) q^{97} + 4 q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{3} + 2q^{7} + O(q^{10}) \) \( 2q - 2q^{3} + 2q^{7} - 8q^{13} - 8q^{17} + 8q^{19} - 4q^{21} + 10q^{23} - 8q^{27} + 8q^{33} + 16q^{39} - 8q^{41} - 14q^{43} + 6q^{47} - 8q^{53} - 8q^{57} + 8q^{59} + 16q^{61} - 2q^{63} + 6q^{67} + 8q^{73} + 8q^{77} + 16q^{79} + 10q^{81} + 10q^{83} + 4q^{87} + 16q^{93} + 24q^{97} + 8q^{99} + O(q^{100}) \)
