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

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

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