Let \(D_{2n}\) denote the dihedral group of order \(2n\). The author constructs an explicit diagonal approximation on the free \(\mathbb{Z}[D_{2n}]\)-resolution of \(\mathbb{Z}\) given by \textit{C. T. C. Wall} [Proc. Camb. Philos. Soc. 57, 251-255 (1961; Zbl 0106.249)]. Using this diagonal approximation a number of examples of cohomology products (with non-trivial coefficients) are computed.
