Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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