Polygon cycles:
In geometry, a circumscribed (polygon cycle) area of a polyhedron is a area that contain the polyhedron & touches every of the polyhedron's vertices. The text circumsphere is sometimes used to denote the similar thing. When it exists, a circumscribed area need not be the least area contain the polyhedron; for example, the tetrahedron formed by a vertex of a cube & its four neighbors has the similar circumsphere as the cube itself, but can be limited within a lesser area having the four near vertices on its equator.
