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