  2. Fox n-coloring - Wikipedia

    en.wikipedia.org/wiki/Fox_n-coloring

    In the mathematical field of knot theory, Fox n-coloring is a method of specifying a representation of a knot group or a group of a link (not to be confused with a link group) onto the dihedral group of order n where n is an odd integer by coloring arcs in a link diagram (the representation itself is also often called a Fox n-coloring).

  3. Covering groups of the alternating and symmetric groups

    en.wikipedia.org/wiki/Covering_groups_of_the...

    The double cover of the alternating group can be constructed via the spin representation that covers the usual linear representation of the alternating group. The double covers can be constructed as spin (respectively, pin) covers of faithful, irreducible, linear representations of A n and S n.

  4. Color scheme - Wikipedia

    en.wikipedia.org/wiki/Color_scheme

    The triadic color scheme is a three-color combination consisting of base color and two colors that are 120 degrees and 240 degrees apart from the base color. [6] Triadic color schemes tend to be quite vibrant. Even when using pale or unsaturated versions of hues, it offers a higher degree of contrast while also retaining the color harmony.

  5. Cayley graph - Wikipedia

    en.wikipedia.org/wiki/Cayley_graph

    In mathematics, a Cayley graph, also known as a Cayley color graph, Cayley diagram, group diagram, or color group, [1] is a graph that encodes the abstract structure of a group. Its definition is suggested by Cayley's theorem (named after Arthur Cayley ), and uses a specified set of generators for the group.

  6. Color and Symmetry - Wikipedia

    en.wikipedia.org/wiki/Color_and_Symmetry

    Color and Symmetry is a book by Arthur L. Loeb published by Wiley Interscience in 1971. The author adopts an unconventional algorithmic approach to generating the line and plane groups based on the concept of "rotocenter" (the invariant point of a rotation).

    Three-colour symmetry operation of colour group p3[3] 1. Polychromatic symmetry is a colour symmetry which interchanges three or more colours in a symmetrical pattern. It is a natural extension of dichromatic symmetry.
