Presentation

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

A minimal faithful permutation representation — 4 generators on 40 points:

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