Presentation

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

A minimal faithful permutation representation — 3 generators on 40 points:

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