普通立方体是规则多面体的常见示例:它有各种正方形(上、下、前、后、左、右),由几条边(12条边)分隔,这些边在八个角处以特定的方式以三相交。通常,这样的立方体给人的想象是一个非常对称和刚性的物体,即欧几里得的实现;但如果我们相反地考虑一个橡胶副本,那么我们可以想象以奇妙的方式扭曲和扭曲立方体,这破坏了它的对称性。然而,立方体的“组合特征”将在这次破坏企图中幸存下来;仍然会有6个正方形的面,12个边和8个角,像以前一样相互连接。
英文摘要
An ordinary cube is a familiar example of a regular polytope: it has various square faces (top, bottom, front, back, left, right), separated by several edges (twelve of them), which meet by threes in a particular way at the eight corners. Usually such a cube suggests to the imagination a very symmetrical and rigid object, i.e. a Euclidean realization; but if we consider instead a rubber copy, then we can imagine twisting and distorting the cube in fantastic ways which destroy its symmetry. Nevertheless, the `combinatorial features' of the cube would survive this attempt at destruction; there would still be 6 square faces, 12 edges and 8 corners, interconnected as before.
