Presentation

minimal degreeμ(G) = 40
transitive degreeμt(G) = 256

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

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