Abstract
The tetrahedron is a well-known polyhedron. The tetrahedron can be shown with a set of lines (bars) made of 3 points (joints) from the different elements; for instance an edge is a line of 2 vertices and the same edge. The equally linked property means that every element is connected with the same amount of links. The paper explains this property with tetrahedrons and shows different prototypes that can become nice objects.
