Presentation

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

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

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