论文摘要
我们描述了定向的立方体和跨物流的伴随之间的两者。这种对应关系用于证明真正的仿射立方体是在同一类中重新定位的，即可实现的独特立方体。此外，其基本的矩阵是同构的，它是可实现的独特组合立方体。
We describe a bijection between oriented cubes and adjoints of cross-polytopes. This correspondence is used to prove that the real affine cube is, up to reorientation in the same class, the unique oriented cube that is realizable. Moreover, its underlying matroid is, up to isomorphism, the unique combinatorial cube that is realizable over the reals.
