Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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