Presentation

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

A minimal faithful permutation representation — 2 generators on 40 points:

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