<ref name="space filling note">The Hilbert curve map is not a [[homeomorphism]], so it does not preserve topological dimension. The topological dimension and Hausdorff dimension of the image of the Hilbert map in '''R'''<sup>2</sup> are both 2. Note, however, that the topological dimension of the ''graph'' of the Hilbert map (a set in '''R'''<sup>3</sup>) is 1.</ref>
