Translational invariance implies that at least in one direction the object is infinite: for any given point p the set of points with the same properties due to the translational symmetry form the infinite discrete set {p + na | n ∈ Z} = p + Z a.Fundamental domains are e.g. H + [0 1] a for any hyperplane H for which a has an independent direction.
