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