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 movement toward foundationless beekeeping by hobbyist for various reasons. Some of which are listed below: A frame has to be wired so that the wax foundation could be inserted into it. The foundation is then soldered with the wire by using a spur embedder or electric current. Also extant are wax foundations with embedded wire that only need to be inserted into the frame. Wax foundations are made in various sizes, depending on the frame they will be inserted into. If needed, roller knife is used to cut wax foundations. Wax foundation Wax foundation or honeycomb base is a plate
