The heptagonal antitegum, also known as the heptagonal trapezohedron, is an antitegum based on the heptagon, constructed as the dual of a heptagonal antiprism. It has 14 kites as faces, with 2 order–7 and 14 order–3 vertices.
Each face of this polyhedron is a kite with its longer edges times the length of its shorter edges.
