Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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