Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 64

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

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