Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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