This link, consisting of two strands, possesses six-fold rotational symmetry.

One possible starting self-similar link:

After one iteration, it consists of eight strands:

After two iterations, it consists of 44 strands:

A second possible starting self-similar link, that is mathematically the same, but visually distinct from the above:

After one iteration, it consists of eight strands:

After two iterations, it consists of 44 strands:

For both the designs above, the holes form Koch islands in the limit of an infinite number of iterations.br> >br>
