The \(q\)-expansion and trace form are shown below.
Character values
We give the values of \(\chi\) on generators for \(\left(\mathbb{Z}/3024\mathbb{Z}\right)^\times\).
| \(n\) | \(757\) | \(785\) | \(1135\) | \(2593\) |
| \(\chi(n)\) | \(1\) | \(\zeta_{12}^{4}\) | \(-1\) | \(\zeta_{12}^{4}\) |
Embeddings
For each embedding \(\iota_m\) of the coefficient field, the values \(\iota_m(a_n)\) are shown below.
