Presentation

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

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

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