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