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

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

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