In mathematics, a dihedral group is the group of symmetries of a regular polygon, which includes rotations and reflections. Dihedral groups are among the simplest examples of finite groups, and they play an important role in group theory and geometry. The notation for the dihedral group differs in geometry and abstract algebra. In geometry, Dn or Dihn refers t…
Representation Theory of the Dihedral Group $D_{2n}$
Suppose we have the group D2n (for clarity this is the dihedral group of order 2n, as notation can differ between texts). We can describe this group as follows: σ, τ | σn = 1, τ2 = 1, τστ = σ − …
3.3: Dihedral Groups (Group of Symmetries)
Definition: Dihedral Groups. A dihedral group is a group of symmetries of a regular polygon with n sides, where n is a positive integer. The dihedral group of order 2n, denoted by D_n, is …

Dihedral Group -- from Wolfram MathWorld
Dihedral groups D_n are non-Abelian permutation groups for n>2. The nth dihedral group is represented in the Wolfram Language as DihedralGroup[n]. One group presentation …
