Presentation

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

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

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