Presentation

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

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

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