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)(11,18)(13,22)(14,20)(16,19)(17,24)(21,23);(7,8)(9,11,13,16,14,17,23,10)(12,18,22,19,20,24,21,15);(7,8)(9,10,13,17,14,16,23,11)(12,19,21,24,20,15,22,18)
