Presentation

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

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

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