Presentation

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

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

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