Linear representation theory of special affine group:SA(2,3)

Degrees of irreducible representations
The degrees of irreducible representations can be determined using GAP's CharacterDegrees and SA functions (note the SA function is not in-built):

gap> CharacterDegrees(SA(2,3)); [ [ 1, 3 ], [ 2, 3 ], [ 3, 1 ], [ 8, 3 ] ]
