Presentation

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

A minimal faithful permutation representation — 4 generators on 24 points:

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