$q$-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.

\(f(q)\) \(=\) \( q + ( -2 + i ) q^{5} -2 i q^{7} +O(q^{10})\) \( q + ( -2 + i ) q^{5} -2 i q^{7} + 2 q^{11} + 2 i q^{13} + 6 i q^{17} + 8 q^{19} -4 i q^{23} + ( 3 - 4 i ) q^{25} + 8 q^{29} + ( 2 + 4 i ) q^{35} + 10 i q^{37} -2 q^{41} + 12 i q^{43} + 3 q^{49} -10 i q^{53} + ( -4 + 2 i ) q^{55} + 6 q^{59} + 2 q^{61} + ( -2 - 4 i ) q^{65} -8 i q^{67} -4 q^{71} + 4 i q^{73} -4 i q^{77} -8 q^{79} + 4 i q^{83} + ( -6 - 12 i ) q^{85} + 6 q^{89} + 4 q^{91} + ( -16 + 8 i ) q^{95} -8 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 4q^{5} + O(q^{10}) \) \( 2q - 4q^{5} + 4q^{11} + 16q^{19} + 6q^{25} + 16q^{29} + 4q^{35} - 4q^{41} + 6q^{49} - 8q^{55} + 12q^{59} + 4q^{61} - 4q^{65} - 8q^{71} - 16q^{79} - 12q^{85} + 12q^{89} + 8q^{91} - 32q^{95} + O(q^{100}) \)

Character values
