Presentation

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

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

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