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

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

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