Presentation

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

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

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