Presentation

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

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

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