Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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