Webnating knot is both almost-alternating and toroidally alternating. Proposition 1. Let K be an alternating knot. Then K has an almost-alternating diagram and a toroidally alternating diagram. Proof. By [4], every alternating knot has an almost-alternating diagram. By [3], we can nd a toroidally alternating diagram from an almost-alternating diagram. Web1 de nov. de 2024 · 1. Introduction. In general position of planar diagrams of knots and links, two strands meet at every crossing.

Such triple-point diagrams have been studied in several …
