Presentation

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

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

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