Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 256

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

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