Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 3 generators on 40 points:

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