  3. Polyhedral graph - Wikipedia

    en.wikipedia.org/wiki/Polyhedral_graph

    The polyhedral graph formed as the Schlegel diagram of a regular dodecahedron. In geometric graph theory, a branch of mathematics, a polyhedral graph is the undirected graph formed from the vertices and edges of a convex polyhedron. Alternatively, in purely graph-theoretic terms, the polyhedral graphs are the 3-vertex-connected, planar graphs.

    en.wikipedia.org/wiki/Archimedean_graph

    In the mathematical field of graph theory, an Archimedean graph is a graph that forms the skeleton of one of the Archimedean solids. There are 13 Archimedean graphs, and all of them are regular , polyhedral (and therefore by necessity also 3-vertex-connected planar graphs ), and also Hamiltonian graphs .

    v3.3.3.3.3 The above shapes may also be realized as slices orthogonal to the long diagonal of a tesseract . If this diagonal is oriented vertically with a height of 1, then the first five slices above occur at heights r , ⁠ 3 / 8 ⁠ , ⁠ 1 / 2 ⁠ , ⁠ 5 / 8 ⁠ , and s , where r is any number in the range 0 < r ≤ ⁠ 1 / 4 ⁠ , and s ...

    The web graph W 4,2 is a cube. The web graph W n,r is a graph consisting of r concentric copies of the cycle graph C n, with corresponding vertices connected by "spokes". Thus W n,1 is the same graph as C n, and W n,2 is a prism. A web graph has also been defined as a prism graph Y n+1, 3, with the edges of the outer cycle removed. [7] [10]

  9. Regular polyhedron - Wikipedia

    en.wikipedia.org/wiki/Regular_polyhedron

    The Platonic solids known to antiquity are the only integer solutions for m ≥ 3 and n ≥ 3. The restriction m ≥ 3 enforces that the polygonal faces must have at least three sides. When considering polyhedra as a spherical tiling , this restriction may be relaxed, since digons (2-gons) can be represented as spherical lunes, having non-zero ...
