Presentation

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

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

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