Presentation

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

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

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