Presentation

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

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

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