Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/774\mathbb{Z}\right)^\times\).

\(n\) \(173\) \(433\)
\(\chi(n)\) \(-1\) \(-1\)

Coefficient data

For each \(n\) we display the coefficients of the \(q\)-expansion \(a_n\), the Satake parameters \(\alpha_p\), and the Satake angles \(\theta_p = \textrm{Arg}(\alpha_p)\). You can download additional coefficients here.
