Presentation

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

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

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