Presentation

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

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

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