Presentation

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

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

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