Presentation

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

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

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