Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 3 generators on 24 points:

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