Presentation

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

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

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