Another example is the union of all dihedral groups.

The Sylow 2-subgroup is a dihedral group of order 8.

It is the dihedral group of order 2, also known as the Klein four-group.

This is the Coxeter complex of the infinite dihedral group.

These elements generate the dihedral group of the square.

D refers to the dihedral group of eight elements.

Its symmetry group is the dihedral group of order 6 D.

Their symmetry group, the dihedral group of order 4, has eight elements.

For example, in the infinite dihedral group, which has presentation:

The center of the dihedral group D is trivial when n is odd.

Consider for example the dihedral group D of symmetries of a square.

It is open even for dihedral groups, although for special sets of generators some progress has been made.

Dihedral group is like the cyclic group, but also includes reflections.

The first table, d, is based on multiplication in the dihedral group D.

There are several important generalizations of the dihedral groups:

The girth of the dihedral group is 2.

Another notation is Dih, because it is a dihedral group.

For this reason the dicyclic group is also known as the "'binary dihedral group"'.

As an example of a group cycle graph, consider the dihedral group Dih.

Another motivating example is the infinite dihedral group .

The associated rotations and reflection (mathematics) make up the dihedral group D'n'.

The infinite dihedral group has a cyclic subgroup of index 2, which is necessarily normal.

Therefore it is also called a dihedron (Greek: solid with two faces), which explains the name dihedral group.

It is abelian, and isomorphic to the dihedral group of order (cardinality) 4.

Dihedral groups Dih consists of an n-element cycle and n 2-element cycles.
