$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a primitive root of unity \(\zeta_{12}\). We also show the integral \(q\)-expansion of the trace form.

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

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/975\mathbb{Z}\right)^\times\).

\(n\)	\(301\)	\(326\)	\(352\)
\(\chi(n)\)	\(-\zeta_{12}^{2}\)	\(1\)	\(-1\)
