Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 128

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

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