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

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

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