$q$-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.

\(f(q)\) \(=\) \( q +O(q^{10})\) \( q + 2 q^{13} -8 \zeta_{6} q^{19} + ( 5 - 5 \zeta_{6} ) q^{25} + ( 4 - 4 \zeta_{6} ) q^{31} + 10 \zeta_{6} q^{37} + 8 q^{43} -14 \zeta_{6} q^{61} + ( 16 - 16 \zeta_{6} ) q^{67} + ( 10 - 10 \zeta_{6} ) q^{73} + 4 \zeta_{6} q^{79} + 14 q^{97} +O(q^{100})\)
\(\operatorname{Tr}(f)(q)\) \(=\) \( 2q + O(q^{10}) \) \( 2q + 4q^{13} - 8q^{19} + 5q^{25} + 4q^{31} + 10q^{37} + 16q^{43} - 14q^{61} + 16q^{67} + 10q^{73} + 4q^{79} + 28q^{97} + O(q^{100}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1764\mathbb{Z}\right)^\times\).

\(n\) \(785\) \(883\) \(1081\)
\(\chi(n)\) \(1\) \(1\) \(-\zeta_{6}\)
