Character values

We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/1140\mathbb{Z}\right)^\times\).

\(n\) \(457\) \(571\) \(761\) \(781\)
\(\chi(n)\) \(-1\) \(1\) \(1\) \(e\left(\frac{1}{3}\right)\)

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.
