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.

orbit label order primitive -1 1
\(\chi_{4}(1,\cdot)\) 4.a 1 No \(1\) \(1\)
\(\chi_{4}(3,\cdot)\) 4.b 2 Yes \(-1\) \(1\)
