Presentation

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

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

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