   Tesseract
   Definition (undergraduate level) A four-dimensional object; it is analogous to a cube. The 'volume' of a tesseract with edge length x is x 4 . <br /> It has 16 vertices, 32 edges, 24 faces and 8 cells; the cells are cubes. Its dual is the 16-cell. It can be used to tessellate four-dimensional space.<br /> The dual of the tesseract is th ...

   The four-dimensional analogue of a cube, also known as a 4-space hypercube or an 8-cell. The name, possibly coined by Charles Hinton, comes from tesser, meaning four, and aktis, meaning ray, thus 'four rays.' Just as a cube is obtained by 'thickening' a square in the third dimension, which can be ...
