In mathematics, D 3 (sometimes alternatively denoted by D 6) is the dihedral group of degree 3 and order 6. It equals the symmetric group S 3. It is also the smallest non-abelian group. [1] This page illustrates many group concepts using this group as example.

In mathematics, a dihedral group is the group of symmetries of a regular polygon, [1] [2] which includes rotations and reflections. Dihedral groups are among the simplest examples of finite groups, and they play an important role in group theory, geometry, and chemistry. [3] The notation for the dihedral group differs in geometry and abstract ...
This article lists the groups by Schoenflies notation, Coxeter notation, [1] orbifold notation, [2] and order. John Conway uses a variation of the Schoenflies notation, based on the groups' quaternion algebraic structure, labeled by one or two upper case letters, and whole number subscripts.
The irreducible complex characters of a finite group form a character table which encodes much useful information about the group G in a concise form. Each row is labelled by an irreducible character and the entries in the row are the values of that character on any representative of the respective conjugacy class of G (because characters are class functions).
The position of each atom is determined by the nature of the chemical bonds by which it is connected to its neighboring atoms. The molecular geometry can be described by the positions of these atoms in space, evoking bond lengths of two joined atoms, bond angles of three connected atoms, and torsion angles ( dihedral angles ) of three ...
The generalized quaternion group, the dihedral group, and the quasidihedral group of order 2 n all have nilpotency class n − 1, and are the only isomorphism classes of groups of order 2 n with nilpotency class n − 1. The groups of order p n and nilpotency class n − 1 were the beginning of the classification of all p-groups via coclass.
English: The number on the rim of the node circle indicates an order of an element the node represents. Node's colour marks conjugacy class of element with exception that elements of group's center have the same colour (light gray) despite every one of them being of its own conjugacy class of one element.
