Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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