Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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