The smallest convex set of points in which a given set of points is contained.
The convex hull of a compact subset of an infinite dimensional topological vector space need not be a compact set.

Thus, the polyhedron and the convex hull of the set of its vertices coincide, which was to be proved. Since the convex hull of a set M is determined uniquely from M, Theorem 1 implies that a bounded solid polyhedron and its surface, i.e., a closed convex polyhedron, are determined uniquely from its vertices.
