Presentation

minimal degreeμ(G) = 24
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 3 generators on 24 points:

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