Presentation

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

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

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