Presentation

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

A minimal faithful permutation representation — 3 generators on 24 points:

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