==Tessellations== Every polyiamond of order 8 or less tiles the plane, except for the V-heptiamond.<ref>[http://www.mathpuzzle.com/Tessel.htm "All of the polyiamonds of order eight or less, with the exception of one of the heptiamonds will tessellate the plane. The exception is the V-shaped heptiamond. Gardner (6th book p.248) posed the problem of identifying this heptiamond and reproduced an impossibilty proof of Gregory. However, in combination with other heptiamonds or other polyiamonds, tesselations using this V-shaped heptiamond can be achieved."]</ref>
