Tie a slip knot and chain until it overlaps by one chain stitch when wrapped around the tubing. I wouldn't reccomend any shorter than this as it would be difficult to get the finished rings to lie flat. Tell your friends! Borromean rings form a link composed of three unknots linked as shown above: these two representation, mirror images of one another, seem different, but in fact give topologically equivalent links (go from one to the other by pushing two of the rings into the third one)..

But if you sit down with three binder rings or other rigid, perfect circles, you will not be able to recreate it. In mathematics, the Borromean rings are three simple closed curves in three-dimensional space that are topologically linked and cannot be separated from each other, but that break apart into two unknotted and unlinked loops when any one of the three is cut or removed. Keep crocheting until it's roughly the same length as the tubing, then cut the yarn leaving plenty for sewing the ends together later, and pull through the last crochet loop.

Assuming that all rings are flat they cannot constitute this symbol without distortions or breaks. The Three-Torus Topology is the study of the large-scale properties of an object, the things that remain the same even when you stretch or squish the object, so the exact geometry of the figure is inconsequential.
