A problem posed in their paper is to characterize Eulerian embedded graphs (not necessarily checkerboard colourable) which contain two orthogonal A-trails. In this … Webfor checkerboard colourable link diagrams on other surfaces, in which case the resulting graph is embedded on the surface. However, as this construction requires checkerboard colourability, Tait graphs cannot be constructed for arbitrary link diagrams on a surface, or arbitrary virtual link diagrams. how many people installed roblox
