$q$-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.

\(f(q)\) \(=\) \( q - q^{3} + 3 i q^{5} -3 i q^{7} -2 q^{9} +O(q^{10})\) \( q - q^{3} + 3 i q^{5} -3 i q^{7} -2 q^{9} + ( -2 - 3 i ) q^{13} -3 i q^{15} + 3 q^{17} -6 i q^{19} + 3 i q^{21} + 6 q^{23} -4 q^{25} + 5 q^{27} + 9 q^{35} -3 i q^{37} + ( 2 + 3 i ) q^{39} - q^{43} -6 i q^{45} -3 i q^{47} -2 q^{49} -3 q^{51} + 6 q^{53} + 6 i q^{57} -6 i q^{59} + 8 q^{61} + 6 i q^{63} + ( 9 - 6 i ) q^{65} -12 i q^{67} -6 q^{69} -15 i q^{71} + 6 i q^{73} + 4 q^{75} -10 q^{79} + q^{81} + 6 i q^{83} + 9 i q^{85} -6 i q^{89} + ( -9 + 6 i ) q^{91} + 18 q^{95} -12 i q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q - 2q^{3} - 4q^{9} + O(q^{10}) \) \( 2q - 2q^{3} - 4q^{9} - 4q^{13} + 6q^{17} + 12q^{23} - 8q^{25} + 10q^{27} + 18q^{35} + 4q^{39} - 2q^{43} - 4q^{49} - 6q^{51} + 12q^{53} + 16q^{61} + 18q^{65} - 12q^{69} + 8q^{75} - 20q^{79} + 2q^{81} - 18q^{91} + 36q^{95} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/832\mathbb{Z}\right)^\times\).
