Bidiakis cube Bidiakis cube In the mathematical field of graph theory, the Bidiakis cube is a 3-regular graph with 12 vertices and 18 edges. The Bidiakis cube is a cubic Hamiltonian graph and can be defined by the LCF notation [-6,4,-4]. The Bidiakis cube can also be constructed from a cube by adding edges across the top and bottom faces which connect the centres of opposite sides of the faces. The two additional edges need to be perpendicular to each other. With this construction, the Bidiakis cube is a polyhedral graph, and can be realized as a convex polyhedron. Therefore, by Steinitz's
Cosmic Cube machine to get the Cube from the ocean floor into which it had dropped during a battle between the Red Skull and Captain America. A Cube—together with 11 other items from Marvel and DC Comics continuity—was used once again as a plot device in intercompany crossover series "JLA/Avengers" #1–4 (Sept. 2003–April 2004: bi-monthly). The Cube also shows up in "Captain America" vol. 5. Aleksander Lukin wants the Cube and is willing to trade the Red Skull for it. The Red Skull claims he does not have it, but has spies out looking for it. Five years later, the Skull is
