$q$-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.

\(f(q)\)	\(=\)	\( q + (2 \zeta_{6} - 1) q^{2} - q^{4} + ( - \zeta_{6} - 1) q^{5} + (\zeta_{6} + 1) q^{7} + (2 \zeta_{6} - 1) q^{8}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 2 q - 2 q^{4} - 3 q^{5} + 3 q^{7}+O(q^{10}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/351\mathbb{Z}\right)^\times\).

\(n\)	\(28\)	\(326\)
\(\chi(n)\)	\(\zeta_{6}\)	\(-1 + \zeta_{6}\)

Embeddings
