Linear representation theory of Mathieu group:M24

Degrees of irreducible representations
These can be computed using the CharacterDegrees, GAP:CharacterTable, and MathieuGroup functions:

gap> CharacterDegrees(CharacterTable(MathieuGroup(24))); [ [ 1, 1 ], [ 23, 1 ], [ 45, 2 ], [ 231, 2 ], [ 252, 1 ], [ 253, 1 ], [ 483, 1 ], [ 770, 2 ], [ 990, 2 ], [ 1035, 3 ], [ 1265, 1 ], [ 1771, 1 ],  [ 2024, 1 ], [ 2277, 1 ], [ 3312, 1 ], [ 3520, 1 ], [ 5313, 1 ],  [ 5544, 1 ], [ 5796, 1 ], [ 10395, 1 ] ]
