Presentation

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

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

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