 * &lt;p&gt; Icosahedron is a polyhedron with 12 vertices and, 20 faces, where a regular icosahedron is a Platonic solid. All faces are regular (equilateral) triangles. In comparison to the other icosahedra examples, this this default Icosahedron can be considered at level 0, meaning that no further subdivision has occurred from the platonic solid. &lt;/p&gt;
