$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{6}\). We also show the integral \(q\)-expansion of the trace form.

\(f(q)\) \(=\) \( q + ( 3 - 2 \zeta_{6} ) q^{7} +O(q^{10})\) \( q + ( 3 - 2 \zeta_{6} ) q^{7} + ( -2 + \zeta_{6} ) q^{13} + ( 5 - 10 \zeta_{6} ) q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} + ( -12 + 6 \zeta_{6} ) q^{31} + q^{37} + ( 8 - 8 \zeta_{6} ) q^{43} + ( 5 - 8 \zeta_{6} ) q^{49} + ( 5 + 5 \zeta_{6} ) q^{61} -11 \zeta_{6} q^{67} + ( -1 + 2 \zeta_{6} ) q^{73} + ( 13 - 13 \zeta_{6} ) q^{79} + ( -4 + 5 \zeta_{6} ) q^{91} + ( -11 - 11 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + 4q^{7} + O(q^{10}) \) \( 2q + 4q^{7} - 3q^{13} + 5q^{25} - 18q^{31} + 2q^{37} + 8q^{43} + 2q^{49} + 15q^{61} - 11q^{67} + 13q^{79} - 3q^{91} - 33q^{97} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/2268\mathbb{Z}\right)^\times\).

\(n\) \(325\) \(1135\) \(1541\)
\(\chi(n)\) \(-1\) \(1\) \(\zeta_{6}\)
