Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 240

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

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