Presentation

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

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

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