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