Tetrapod

The tetrapod or tepod is a semi-uniform polygon that has 8 sides of two different edge lengths. The angles of a tetrapod are always 45 degrees. It is a faceting of the ditetragon.

Vertex coordinates
A tetrapod with minor edge length 1 and major edge length x centered at the origin will have vertex coordinates given by all permutations of:


 * $$(\pm (\frac{x^2}{2}+0.25), \pm 0.5)$$
