Presentation

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

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

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