<p>Decorative knot with twelve crossings, depicted with four-fold symmetry, and having an overall interlaced quasi-cross shape inside an enclosing circle.  This is a variant of <a href="//commons.wikimedia.org/wiki/File:12crossings-fourfold-symmetric.svg" title="File:12crossings-fourfold-symmetric.svg">File:12crossings-fourfold-symmetric.svg</a> (which has all knot crossings at 90° angles), and is topologically equivalent to <a href="//commons.wikimedia.org/wiki/File:12crossings-4symmetrical-square.svg" title="File:12crossings-4symmetrical-square.svg">File:12crossings-4symmetrical-square.svg</a> (see <a rel="nofollow" class="external free" href="http://katlas.math.toronto.edu/wiki/K12a975">http://katlas.math.toronto.edu/wiki/K12a975</a> ).
