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