minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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