Presentation

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

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

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