$q$-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.

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

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1872\mathbb{Z}\right)^\times\).
