Presentation

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

A minimal faithful permutation representation — 4 generators on 40 points:

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