Presentation

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

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

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