A point of a topological space is a cut
point of if is disconnected. Further, if has precisely components for some natural number we will say that has cut point order . If each point of a
connected space is a cut point of , we will say that is a cut point space. Herein we construct a space so that is a connected Hausdorff space and each point of is a cut point of order three. We also note that there is no uncountable separable cut point space with each point a cut point of order three and
therefore no such space may be embedded in a Euclidean space.
