minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 64

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

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