Presentation

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

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

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