Presentation

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

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

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