Presentation

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

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

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