Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 256

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

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