Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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