Presentation

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

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

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