Presentation

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

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

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