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 ...

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.

We will determine the ring structure of the Hochschild cohomology HH*(ZD2n) of the integral group ring of the dihedral group D2nof order 2n. Journal Information The aim of this journal is to publish ...
