$q$-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.

\(f(q)\) \(=\) \( q + 9 i q^{5} -7 q^{7} +O(q^{10})\) \( q + 9 i q^{5} -7 q^{7} + 9 i q^{11} + 14 q^{13} + 18 i q^{17} + 8 q^{19} -36 i q^{23} -56 q^{25} -18 i q^{29} + 35 q^{31} -63 i q^{35} + 44 q^{37} + 36 i q^{41} -22 q^{43} -54 i q^{47} + 9 i q^{53} -81 q^{55} + 18 i q^{59} + 20 q^{61} + 126 i q^{65} + 14 q^{67} + 126 i q^{71} + 89 q^{73} -63 i q^{77} + 110 q^{79} + 27 i q^{83} -162 q^{85} + 18 i q^{89} -98 q^{91} + 72 i q^{95} + 11 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 14q^{7} + O(q^{10}) \) \( 2q - 14q^{7} + 28q^{13} + 16q^{19} - 112q^{25} + 70q^{31} + 88q^{37} - 44q^{43} - 162q^{55} + 40q^{61} + 28q^{67} + 178q^{73} + 220q^{79} - 324q^{85} - 196q^{91} + 22q^{97} + O(q^{100}) \)
