Presentation

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

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

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