How to Braid More Than 3 Strands

At work the other day, one of the engineers in lab mentioned that braiding power wires was a good way to keep them all together and have any interference affect them all equally, so that the relative voltages would remain constant. It’s a more complicated version of the twisted pair.

Anyway, I realized I had 4 cables, and I only knew how to braid 3 strands. So of course I spent the next few minutes figuring out how to braid more than 3 strands. It turns out it’s easy. You just take the rightmost strand, and moving to the left, weave it over, then under, then over. Then do this process again with the new rightmost strand. And then the new rightmost strand, etc., etc. You can do the same thing with any number of strands, always start with the right and weave to the left. My finely-crafted Windows Paint picture to the right shows the basic idea.
