<p>Fifth iteration of the cross (non-saltire) version of the "box fractal" or "Vicsek fractal", derived by iteratively replacing a square with a saltire or cross of five smaller squares on a 3-by-3 subgrid.
</p>
For the first four iterations of both forms of the fractal, see <a href="//commons.wikimedia.org/wiki/File:Box_or_Vicsek_Fractal_4-iterations.svg" title="File:Box or Vicsek Fractal 4-iterations.svg">File:Box or Vicsek Fractal 4-iterations.svg</a>.
