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