$q$-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.

\(f(q)\) \(=\) \( q + ( -1 + \zeta_{6} ) q^{7} +O(q^{10})\) \( q + ( -1 + \zeta_{6} ) q^{7} -5 \zeta_{6} q^{13} + 7 q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} -4 \zeta_{6} q^{31} + 11 q^{37} + ( 8 - 8 \zeta_{6} ) q^{43} + 6 \zeta_{6} q^{49} + ( 1 - \zeta_{6} ) q^{61} + 5 \zeta_{6} q^{67} -7 q^{73} + ( 17 - 17 \zeta_{6} ) q^{79} + 5 q^{91} + ( 19 - 19 \zeta_{6} ) q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2 q - q^{7} + O(q^{10}) \) \( 2 q - q^{7} - 5 q^{13} + 14 q^{19} + 5 q^{25} - 4 q^{31} + 22 q^{37} + 8 q^{43} + 6 q^{49} + q^{61} + 5 q^{67} - 14 q^{73} + 17 q^{79} + 10 q^{91} + 19 q^{97} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1296\mathbb{Z}\right)^\times\).

\(n\) \(325\) \(1135\) \(1217\)
\(\chi(n)\) \(1\) \(1\) \(-\zeta_{6}\)
