Presentation

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

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

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