Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 128

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

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