Presentation

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

A minimal faithful permutation representation — 7 generators on 24 points:

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