Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 64

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

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