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