Presentation

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

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

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