Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/2416\mathbb{Z}\right)^\times\).

\(n\) \(303\) \(1813\) \(1969\)
\(\chi(n)\) \(1\) \(1\) \(-1\)

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.
