Presentation

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

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

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