Knots on the Cubic Lattice
Yuanan Diao showed (Journal of Knot Theory and Its Ramifications vol 2. #4 (1993) pp 413-425)
that this polygon with 24 vertices is a minimal trefoil on the cubic lattice,
and that no knots other than trefoils are possible using only 24 vertices.
Take a look at this knot
in stereo 3D.
Examine this knot
with an interactive 3D model viewer (requires Java).
