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