A free bimodule resolution is constructed for the integral group ring of the dihedral group of order $4m$. This resolution is applied for a description, in terms of generators and defining relations, of the Hochschild cohomology algebra of this group ring.
Keywords: Free bimodule resolution, integral group ring, dihedral group, Hochschild cohomology algebra.
