Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

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

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