Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 5 generators on 40 points:

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