Summary
| Description |
Decorative knot with nine crossings, depicted with three-fold symmetry. The central portion has a shape like a triquetra. Topologically equivalent to File:9crossings-knot-symmetric-triangles-pseudo-valknut.svg and File:9crossings-knot-symmetric-triangles-quasi-valknut.svg. For a 12-crossing symmetrical knot which visually extends this, see Image:12crossings-rose-rhodonea-limacon-symmetrical-knot.svg . For another (topologically distinct) 9-crossing knot with three-fold symmetry, see File:9crossings-decorative-knot-threefold-incircle.svg . |
