Presentation

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

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

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