Presentation

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

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

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