Presentation

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

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

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