Octagonal antitegum

The octagonal antitegum is an antitegum based on the octagon, constructed as the dual of an octagonal antiprism. It has 16 kites as faces, with 2 order–8 and 16 order–3 vertices. .

Each face of this polyhedron is a kite with its longer edges $$2+\sqrt+\sqrt{\frac{10+7\sqrt2}{2}} ≈ 6.56854$$ times the length of its shorter edges.
