Summary
Figure 8 knot models created by Elizabeth Marshall, Mason Shelley, and Libby Kerr (students in Math 383D Knot Theory Spring 2023).
The figure 8 knot is achiral, meaning that it is equivalent to its mirror image. This equivalence is shown in the following 6 models. Each model shows one stage of the equivalence, and each model differs from the previous one by one or two Reidemeister moves. A detailed explanation of the math behind this equivalence can be found here:
