$q$-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.

\(f(q)\) \(=\) \( q + ( 2 - 3 \zeta_{6} ) q^{7} +O(q^{10})\) \( q + ( 2 - 3 \zeta_{6} ) q^{7} + ( 1 - 2 \zeta_{6} ) q^{13} -7 \zeta_{6} q^{19} + ( -5 + 5 \zeta_{6} ) q^{25} + ( 7 - 7 \zeta_{6} ) q^{31} -\zeta_{6} q^{37} + ( 7 - 14 \zeta_{6} ) q^{43} + ( -5 - 3 \zeta_{6} ) q^{49} + ( 8 - 4 \zeta_{6} ) q^{61} + ( -7 - 7 \zeta_{6} ) q^{67} + ( 9 + 9 \zeta_{6} ) q^{73} + ( 14 - 7 \zeta_{6} ) q^{79} + ( -4 - \zeta_{6} ) q^{91} + ( 8 - 16 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + q^{7} + O(q^{10}) \) \( 2q + q^{7} - 7q^{19} - 5q^{25} + 7q^{31} - q^{37} - 13q^{49} + 12q^{61} - 21q^{67} + 27q^{73} + 21q^{79} - 9q^{91} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1008\mathbb{Z}\right)^\times\).
