Presentation

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

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

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