Presentation

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

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

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