Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

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

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