$q$-expansion

Coefficients of the \(q\)-expansion are expressed in terms of a basis \(1,\beta_1,\beta_2,\beta_3\) for the coefficient ring described below. We also show the integral \(q\)-expansion of the trace form.

\(f(q)\)	\(=\)	\( q + ( - \beta_{3} - \beta_{2}) q^{2} + (2 \beta_{2} + 3 \beta_1 - 2) q^{4} + (5 \beta_{3} - 5 \beta_{2} - 5 \beta_1 - 2) q^{8} + 9 \beta_{2} q^{9}+O(q^{10}) \)
\(\operatorname{Tr}(f)(q)\)	\(=\)	\( 4 q - 3 q^{2} - q^{4} - 18 q^{8} + 18 q^{9}+O(q^{10}) \)

Basis of coefficient ring in terms of a root \(\nu\) of \( x^{4} - x^{3} - x^{2} - 2x + 4 \) :

\(\beta_{1}\)	\(=\)	\( \nu \)
\(\beta_{2}\)	\(=\)	\( ( \nu^{3} + \nu^{2} - \nu - 2 ) / 2 \)
\(\beta_{3}\)	\(=\)	\( ( -\nu^{3} + \nu^{2} + \nu + 2 ) / 2 \)

Character values

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

\(n\)	\(197\)	\(295\)	\(297\)
\(\chi(n)\)	\(-1\)	\(1\)	\(\beta_{2}\)

Embeddings
