Presentation

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

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

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