Presentation

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

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

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