Presentation

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

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

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