Presentation

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

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

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