Presentation

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

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

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