Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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