minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 24 points:

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