$q$-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.

\(f(q)\) \(=\) \( q -4 i q^{7} + 3 q^{9} +O(q^{10})\) \( q -4 i q^{7} + 3 q^{9} -4 q^{11} -2 i q^{13} + 2 i q^{17} + 4 q^{19} -4 i q^{23} -2 q^{29} -8 q^{31} -6 i q^{37} -6 q^{41} -8 i q^{43} + 4 i q^{47} -9 q^{49} + 6 i q^{53} -4 q^{59} + 2 q^{61} -12 i q^{63} -8 i q^{67} + 6 i q^{73} + 16 i q^{77} + 9 q^{81} -16 i q^{83} + 6 q^{89} -8 q^{91} -14 i q^{97} -12 q^{99} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 6q^{9} + O(q^{10}) \) \( 2q + 6q^{9} - 8q^{11} + 8q^{19} - 4q^{29} - 16q^{31} - 12q^{41} - 18q^{49} - 8q^{59} + 4q^{61} + 18q^{81} + 12q^{89} - 16q^{91} - 24q^{99} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1600\mathbb{Z}\right)^\times\).
