Presentation

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

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

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