Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 64

A minimal faithful permutation representation — 5 generators on 40 points:

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