Presentation

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

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

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