Summary
Description | Decorative knot with nine crossings, depicted with three-fold symmetric interlacings inside an overall enclosing circle. For a variant visual form of this, see http://katlas.math.utoronto.ca/wiki/Image:9crossings-decorative-knot-threefold-incircle.png . For other (topologically distinct) 9-crossing knots with three-fold symmetry, see File:knot-9crossings-symmetrical.svg, File:9crossings-threesymmetric-other.svg etc. For a quasi-version of this image with fourfold symmetry, see File:Circular-cross-decorative-knot-12crossings.svg . |
