Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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