Presentation

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

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

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