Presentation

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

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

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