Presentation

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

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

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