Presentation

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

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

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