Presentation

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

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

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