\section{Table of Prime Knots}
A knot's \textit{crossing number} is the minimal number of crossings its projection must contain. \par
Finding a knot's crossing number is a fairly difficult problem.

\vspace{1mm}

This table contains the a 20 smallest prime knots, ordered by crossing number. \par
Mirror images are not included, even if the mirror image produces a nonisomorphic knot.

% Images are from the appendix of the Knot book.
