Polygons all of whose edges meet at right angles are called rectilinear polygons. I am interested in rectilinear polygons with integer distance between each pair of vertices. Such rectilinear polygons are trivial to obtain when restricting oneself to polygons with 4 edges.
Do rectilinear $n$-gons exist that have integer Euclidean distance between each of the $\frac12 n(n-1)$ pairs of vertices for $n>4$?
