Presentation

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

A minimal faithful permutation representation — 2 generators on 40 points:

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