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