Presentation

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

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

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