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

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

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