Presentation

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

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

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