Presentation

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

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

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