Latent symmetry.
A theorem is proven which provides a sufficient condition that an isometry is a symmetry of a composite constructed from a component and a group of isometries. The concept of latent symmetry is broadened and this theorem is applied to deduce latent symmetry of example composites, including an example discussed by Litvin & Wadhawan [Acta Cryst. (2001), A57, 435-441], the latent symmetry of which could not be determined there systematically.
