Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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