Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 32

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

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