Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 40 points:

(1,2,4,6)(3,7,8,5)(9,10,12,14)(11,17,19,24)(13,21,18,16)(15,23,22,20)(25,26,28,30)(27,33,34,40)(29,37,36,32)(31,39,38,35);(1,3,4,8)(2,5,6,7)(10,14)(15,22)(16,21)(17,24)(26,30)(31,38)(32,37)(33,40);(9,11,18,23,12,19,13,20)(10,15,21,24,14,22,16,17);(25,27,29,35,28,34,36,39)(26,31,32,33,30,38,37,40)
