However, there are two different ways of smoothing subsets of the edges of the Reuleaux tetrahedron to form Meissner tetrahedra, surfaces of constant width which were conjectured by to have the minimum volume among all shapes with the same constant width; this conjecture remains unsolved.
There are two different ways of smoothing subsets of the edges of the Reuleaux tetrahedron to form Meissner tetrahedra. This is however. Meissner tetrahedra is surfaces of constant width. These surfaces of constant width were conjectured by. This was to have the minimum volume among all shapes with the same constant width. This conjecture remains unsolved.
