$q$-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.

\(f(q)\)	\(=\)	\( q + (\zeta_{6} - 1) q^{2} + (\zeta_{6} - 2) q^{3} + \zeta_{6} q^{4} + \zeta_{6} q^{5} + ( - 2 \zeta_{6} + 1) q^{6} + ( - 3 \zeta_{6} + 3) q^{7} - 3 q^{8} + ( - 3 \zeta_{6} + 3) q^{9}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 2 q - q^{2} - 3 q^{3} + q^{4} + q^{5} + 3 q^{7} - 6 q^{8} + 3 q^{9}+O(q^{10}) \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/45\mathbb{Z}\right)^\times\).

\(n\)	\(11\)	\(37\)
\(\chi(n)\)	\(-\zeta_{6}\)	\(1\)
