Presentation

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

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

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