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
Bateson's cube Bateson's cube Bateson's cube is a model of the cost–benefit analysis for animal research developed by Professor Patrick Bateson, president of the Zoological Society of London. Bateson's cube evaluates proposed research through three criteria: Bateson suggested that research that does not meet these requirements should not be approved or performed, in accordance with the Animals (Scientific Procedures) Act 1986. It is not intended as a formal model for optimal trade-offs, but rather a tool for making judicial decisions, since the three axes are not in a common currency. The third criterion also does not necessarily have to be medical benefit,
