Presentation

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

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

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