By an argument of a topological nature, the Theorem whose proof has just been completed can be somewhat strengthened. Since the collection of affine equivalence classes of all convex plane bodies of area 1 is a compact set, and since the function assigning to each such equivalence class the minimum area of a p-hexagon containing a representative of that class is continuou s,there exists a minimum value for that function, taken on a specific element of that compact set. Let us denote that minimum value by Δ. We have proved in this \(\Delta < \frac{4}{3}\), thus we can conclude that there exists a number \(d > \frac{3}{4}\) (namely \(d = \Delta ^{ - 1} \)) such that every convex body can be packed in the plane with density at least d. The value of A remains unknown.
