Presentation

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

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

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