Presentation

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

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

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