Presentation

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

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

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