Presentation

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

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

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