Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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