Presentation

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

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

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