Presentation

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

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

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