The wings on modern commercial aircraft are attached to the plane at a slight angle known as a dihedral. This angle allows the plane to achieve the lift it needs to fly, and at the proper angles, ...

We describe Galois extensions where the Galois group is the quasi-dihedral, dihedral or modular group of order 16, and use this description to produce generic polynomials.

In mathematics, a dihedral group is the group of symmetries of a regular polygon, including both rotations and reflections. What is a dihedral group? In mathematics, a dihedral group is the group of ...
