Presentation

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

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

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