Presentation

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

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

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