Presentation

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

A minimal faithful permutation representation — 5 generators on 40 points:

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