Presentation

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

A minimal faithful permutation representation — 2 generators on 40 points:

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