Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 4 generators on 24 points:

(1,2,4,7)(3,5,8,6)(9,10,14,12)(11,17,20,24)(13,22,23,16)(15,18,21,19);(9,11,14,20)(10,15,12,21)(13,18,23,19)(16,24,22,17);(2,5)(3,8)(6,7)(9,12,14,10)(11,15,20,21)(13,22,23,16)(17,18,24,19);(11,18)(13,23)(15,24)(16,22)(17,21)(19,20)
