$q$-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.

\(f(q)\)	\(=\)	\( q + 2 \zeta_{6} q^{2} + \zeta_{6} q^{3} + (4 \zeta_{6} - 4) q^{4} + ( - 3 \zeta_{6} - 3) q^{5} + (2 \zeta_{6} - 2) q^{6} - 8 q^{8} + ( - 8 \zeta_{6} + 8) q^{9}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 2 q + 2 q^{2} + q^{3} - 4 q^{4} - 9 q^{5} - 2 q^{6} - 16 q^{8} + 8 q^{9}+O(q^{10}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/392\mathbb{Z}\right)^\times\).

\(n\)	\(197\)	\(295\)	\(297\)
\(\chi(n)\)	\(-1\)	\(-1\)	\(-1 + \zeta_{6}\)
