A Spacefilling Trefoil Knot
This note describes a (polyhedral) prototile which is topologically equivalent to a trefoil knot and admits a (monohedral) tiling of 3-space.

متن کامل1 The ideal trefoil knot
The most tight conformation of the trefoil knot found by the SONO algorithm is presented. Structure of the set of its self-contact points is analyzed.
متن کاملLength of the tightest trefoil knot.
The physical sense of tight knots provided by the SONO algorithm is discussed. A method allowing one to predict their length is presented. An upper bound for the minimum length of a smooth trefoil knot is determined.
متن کاملPolarization-selective Surfaces Composed of Trefoil Knot Elements
In this paper, we demonstrate that the trefoil knot has the unique property that its forward scattering for circularly polarized wa ̈es exhibits a strong dependence on the handedness of the polarization. Both a single knot element as well as an array of these knots show this ( ) property which could be used in a polarization-selectï e surface PSS . Q 1999 John Wiley & Sons, Inc. Microwave Opt Te...
