![](/common/images/spacer.gif) A braid is a collection of strands which weave over and under one another. In Braids.m, a braid is described by a list {{m1, -m2 ..., mc},s} for a braid with s strands; where strand m1 crosses over strand m2, then strand m2 crosses under the m3, ..., and finally strand mc crosses over mc+1. By joining the ends of the braids in a circle they can be used to represent all knots and links. We can also close up the braid in a slightly different form to get a plat.
