  2. Pentagon - Wikipedia

    en.wikipedia.org/wiki/Pentagon

    The regular pentagon has Dih 5 symmetry, order 10. Since 5 is a prime number there is one subgroup with dihedral symmetry: Dih 1, and 2 cyclic group symmetries: Z 5, and Z 1. These 4 symmetries can be seen in 4 distinct symmetries on the pentagon. John Conway labels these by a letter and group order. [10] Full symmetry of the regular form is ...

  3. List of character tables for chemically important 3D point groups

    en.wikipedia.org/wiki/List_of_character_tables...

    The body of the tables contain the characters in the respective irreducible representations for each respective symmetry operation, or set of symmetry operations. The symbol i used in the body of the table denotes the imaginary unit: i 2 = −1. Used in a column heading, it denotes the operation of inversion.

    [[Category:Multi-column templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Multi-column templates]]</noinclude> to the end of the template code, making sure it starts on the same line as the code's last character.

  5. Configuration (polytope) - Wikipedia

    en.wikipedia.org/wiki/Configuration_(polytope)

    Regular polytopes will have one row and column per k-face element, while other polytopes will have one row and column for each k-face type by their symmetry classes. A polytope with no symmetry will have one row and column for every element, and the matrix will be filled with 0 if the elements are not connected, and 1 if they are connected.

  6. Hexadecagon - Wikipedia

    en.wikipedia.org/wiki/Hexadecagon

    On the regular hexadecagon, there are 14 distinct symmetries. John Conway labels full symmetry as r32 and no symmetry is labeled a1. The dihedral symmetries are divided depending on whether they pass through vertices (d for diagonal) or edges (p for perpendiculars) Cyclic symmetries in the middle column are labeled as g for their central ...

  7. Line group - Wikipedia

    en.wikipedia.org/wiki/Line_group

    A line group is a mathematical way of describing symmetries associated with moving along a line. These symmetries include repeating along that line, making that line a one-dimensional lattice. However, line groups may have more than one dimension, and they may involve those dimensions in its isometries or symmetry transformations.

  8. Template:Col-5 - Wikipedia

    en.wikipedia.org/wiki/Template:Col-5

    The table will have two columns, with column 1 twice (2×) the width of column 2. A border of 2px (1px width on each side) corresponds to a 5%. Therefore, with a 2px border, the width needs to be 95% for the table to fit within the screen.

  9. Pentomino - Wikipedia

    Their symmetry group consists only of the identity mapping. T, and U can be oriented in 4 ways by rotation. They have an axis of reflection aligned with the gridlines. Their symmetry group has two elements, the identity and the reflection in a line parallel to the sides of the squares. V and W also can be oriented in 4 ways by rotation.
