Presentation

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

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

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