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