Presentation

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

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

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