Presentation

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

A minimal faithful permutation representation — 5 generators on 24 points:

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