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

A minimal faithful permutation representation — 5 generators on 24 points:

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