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