Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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