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

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

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