Presentation

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

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

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