Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 512

A minimal faithful permutation representation — 4 generators on 40 points:

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