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