Presentation

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

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

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