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

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

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