Presentation

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

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

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