Presentation

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

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

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