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