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