Trigonal trapezohedral honeycomb into squares. It is dual to the quarter cubic honeycomb with tetrahedral and truncated tetrahedral cells: Trigonal trapezohedral honeycomb The trigonal trapezohedral honeycomb is a uniform space-filling tessellation (or honeycomb) in Euclidean 3-space. Cells are identical trigonal trapezohedron or rhombohedra. John Horton Conway calls it an oblate cubille. This honeycomb can be seen as a rhombic dodecahedral honeycomb, with the rhombic dodecahedra dissected with its center into 4 trigonal trapezohedra or rhombohedra. It is analogous to the regular hexagonal being dissectable into 3 rhombi and tiling the plane as a rhombille. The rhombille tiling is actually an orthogonal projection of
Wax foundation Wax foundation Wax foundation or honeycomb base is a plate made of wax with the base of the honeycomb. It is used in beekeeping to give the bees a foundation on which they can build the honeycomb. Wax foundation is considered one of the most important inventions in modern beekeeping. Wax foundation was invented by German Johannes Mehring in 1857, a few years after Langstroth designed and patented the Langstroth hive on October 5, 1852. Mehring's wax foundation had only the bottom of the cells, and today's base with the foundation of the cells was invented by US beekeeper Samuel
