Presentation

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

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

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