Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 256

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

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