    A set \(E \subseteq \mathbb{R}\) has a similarity decomposition if \(E\) is the union of \(2^{\aleph_0}\) pairwise disjoint subsets \(E_{\xi}\) where each \(E_{\xi}\) is order-isomorphic to \(E\). The author constructs a set \(E\) which has a similarity decomposition and has an order type less than that of \(\mathbb{R}\). This solves an old problem of Ginsburg's.
