Presentation

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

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

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