Presentation

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

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

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