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

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

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