  2. Tesseract - Wikipedia

    en.wikipedia.org/wiki/Tesseract

    The tesseract is one of the six convex regular 4-polytopes. The tesseract is also called an 8-cell, C 8, (regular) octachoron, or cubic prism. It is the four-dimensional measure polytope, taken as a unit for hypervolume. [2] Coxeter labels it the γ 4 polytope. [3]

  3. 4-polytope - Wikipedia

    en.wikipedia.org/wiki/4-polytope

    The most familiar 4-polytope is the tesseract or hypercube, the 4D analogue of the cube. The convex regular 4-polytopes can be ordered by size as a measure of 4-dimensional content (hypervolume) for the same radius. Each greater polytope in the sequence is rounder than its predecessor, enclosing more content [5] within the same radius. The 4 ...

  4. Four-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Four-dimensional_space

    The 4-volume or hypervolume in 4D can be calculated in closed form for simple geometrical figures, such as the tesseract (s 4, for side length s) and the 4-ball (/ for radius r). Reasoning by analogy from familiar lower dimensions can be an excellent intuitive guide, but care must be exercised not to accept results that are not more rigorously ...

  5. Regular 4-polytope - Wikipedia

    en.wikipedia.org/wiki/Regular_4-polytope

    The tesseract is one of 6 convex regular 4-polytopes. In mathematics, a regular 4-polytope or regular polychoron is a regular four-dimensional polytope.They are the four-dimensional analogues of the regular polyhedra in three dimensions and the regular polygons in two dimensions.

  6. Hypercube - Wikipedia

    en.wikipedia.org/wiki/Hypercube

    In geometry, a hypercube is an n-dimensional analogue of a square (n = 2) and a cube (n = 3); the special case for n = 4 is known as a tesseract.It is a closed, compact, convex figure whose 1-skeleton consists of groups of opposite parallel line segments aligned in each of the space's dimensions, perpendicular to each other and of the same length.

  7. Cantellated tesseract - Wikipedia

    en.wikipedia.org/wiki/Cantellated_tesseract

    The cantellated tesseract, bicantellated 16-cell, or small rhombated tesseract is a convex uniform 4-polytope or 4-dimensional polytope bounded by 56 cells: 8 small rhombicuboctahedra, 16 octahedra, and 32 triangular prisms.

  8. 6-cube - Wikipedia

    en.wikipedia.org/wiki/6-cube

    In geometry, a 6-cube is a six-dimensional hypercube with 64 vertices, 192 edges, 240 square faces, 160 cubic cells, 60 tesseract 4-faces, and 12 5-cube 5-faces. It has Schläfli symbol {4,3 4}, being composed of 3 5-cubes around each 4-face. It can be called a hexeract, a portmanteau of tesseract (the 4-cube) with hex for six (dimensions) in ...

  9. Rectified tesseract - Wikipedia

    en.wikipedia.org/wiki/Rectified_tesseract

    In geometry, the rectified tesseract, rectified 8-cell is a uniform 4-polytope (4-dimensional polytope) bounded by 24 cells: 8 cuboctahedra, and 16 tetrahedra. It has half the vertices of a runcinated tesseract , with its construction, called a runcic tesseract .
