Problem with formulations?

So... if S = {(1, 2), (2, -1), (-1, -2), (-2, 1)}, then S would seem to be orthogonally convex according to the first paragraph. But the end of the second paragraph suggests that (0, 0) should belong to the orthogonally convex hull of S. What's the deal? Melchoir 22:31, 10 November 2006 (UTC)[reply]
