Presentation

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

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

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