Presentation

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

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

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