Presentation

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

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

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