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

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

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