Characters
Each row describes a character. When available, the columns show the orbit label, order of the character, whether the character is primitive, and several values of the character.
| Character | Orbit | Order | Primitive | \(-1\) | \(1\) |
|---|---|---|---|---|---|
| \(\chi_{4}(1,\cdot)\) | 4.a | 1 | no | \(1\) | \(1\) |
| \(\chi_{4}(3,\cdot)\) | 4.b | 2 | yes | \(-1\) | \(1\) |
