<p>I know that in the smooth category the following is true. There are at most countable many embedded moebius bands in euclidean 3-space. Is this also true in topological category? </p>

<p>There are at most countably many disjoint embeddings of homeomorphic images of a non-orientable hypersurface in $\mathbb R^k$. This is theorem 2 in <a href="http://www.springerlink.com/content/k44tq18411324015/" rel="nofollow">"An uncountable family of disjoint spatial continua in Euclidean space"</a> by V.K. Ionin and Yu.G. Nikonorov. </p>
