Presentation

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

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

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