Presentation

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

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

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