Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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