Decorative knot with nine crossings, depicted with three-fold symmetry.  Topologically equivalent to <a href="//commons.wikimedia.org/wiki/File:Knot-9crossings-symmetrical.svg" title="File:Knot-9crossings-symmetrical.svg">File:Knot-9crossings-symmetrical.svg</a>, but this version is based on triangles (rather than circles), and so appears like a more complex version of a <a href="//commons.wikimedia.org/wiki/Valknut" title="Valknut">Valknut</a>.  For an alternative more open version, see <a href="//commons.wikimedia.org/wiki/File:9crossings-knot-symmetric-triangles-pseudo-valknut.svg" title="File:9crossings-knot-symmetric-triangles-pseudo-valknut.svg">File:9crossings-knot-symmetric-triangles-pseudo-valknut.svg</a>.
