Kauffman's conjecture on detecting knot chirality by the Kauffman polynomial

Let $K$ be a knot, let $\overline{K}$ denote its mirror image, and let $-\overline{K}$ denote the mirror image with reversed orientation. The Kauffman polynomial of $K$ is denoted by $F_K(a,z)$. Kauffman's conjecture. If $K$ is not isotopic to its mirror image ($\overline{K}$ or $-\overline{K}$), then

$$F_K(a,z)\neq F_{\overline{K}}(a,z).$$

The conjecture asserts that the Kauffman polynomial detects chirality in knots, despite the invariant's general inability to distinguish some links from their mirror images. Its status is open in the supplied source context.
