On weakly-neighbourly polyhedra
The author calls a convex polytope \(P\) in an \(n\)-dimensional affine space weakly-neighbourly if the intersection of any two diagonals of \(P\) is the empty set, a common endpoint or the common midpoint of each of the diagonals. The subject of the paper is then the affine classification of weakly-neighbourly polytopes in a three-dimensional affine space.
