Presentation

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

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

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