$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\ldots,\beta_{5}\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\)	\(=\)	\( q + ( - \beta_{5} + \beta_1) q^{2} + (\beta_{5} + \beta_{4} + \beta_{2} - 1) q^{4} + (2 \beta_{4} + \beta_{2} - 2) q^{5} + \beta_{4} q^{7} + (\beta_{3} - \beta_1 + 2) q^{8}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 6 q - q^{2} - 3 q^{4} - 5 q^{5} + 3 q^{7} + 12 q^{8}+O(q^{10}) \)

Basis of coefficient ring in terms of a root \(\nu\) of \( x^{6} - 3x^{5} + 10x^{4} - 15x^{3} + 19x^{2} - 12x + 3 \) :

\(\beta_{1}\)	\(=\)	\( \nu^{2} - \nu + 2 \)
\(\beta_{2}\)	\(=\)	\( ( -\nu^{5} + \nu^{4} - 8\nu^{3} + 5\nu^{2} - 18\nu + 6 ) / 3 \)
\(\beta_{3}\)	\(=\)	\( \nu^{4} - 2\nu^{3} + 6\nu^{2} - 5\nu + 3 \)
\(\beta_{4}\)	\(=\)	\( ( -2\nu^{5} + 5\nu^{4} - 16\nu^{3} + 19\nu^{2} - 21\nu + 9 ) / 3 \)
\(\beta_{5}\)	\(=\)	\( ( 2\nu^{5} - 5\nu^{4} + 19\nu^{3} - 22\nu^{2} + 30\nu - 9 ) / 3 \)

Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/189\mathbb{Z}\right)^\times\).
