Red Devil — Just remember the difference between 'geodetic' and 'geodesic'. The bomber has a diamond lattice, where a proper geodesic has triangular (or 'kagame') lattice.

The result is that any vertex is surrounded by a constraining hexagon, where the geodetic has four rhomuses (rhombi?).

See also Walther Bauersfeld. He built the first geodesic dome for his planetarium.
