Presentation

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

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

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