Presentation

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

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

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