Presentation

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

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

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