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