The 7-cubic honeycomb or hepteractic honeycomb is the only regular space-filling tessellation (or honeycomb) in Euclidean 7-space. It is analogous to the square tiling of the plane and to the cubic honeycomb of 3-space. There are many different Wythoff constructions of this honeycomb.
The vertex arrangement of the 7-demicubic honeycomb is the D 7 lattice. [1] The 84 vertices of the rectified 7-orthoplex vertex figure of the 7-demicubic honeycomb reflect the kissing number 84 of this lattice. [2] The best known is 126, from the E 7 lattice and the 3 31 honeycomb. The D + 7 packing (also called D 2 7) can be constructed by the ...
Honeycomb in the "supers" that are not used for brood (e.g. by the placement of a queen excluder) stays light-colored. Numerous wasps , especially Polistinae and Vespinae , construct hexagonal prism-packed combs made of paper instead of wax; in some species (such as Brachygastra mellifica ), honey is stored in the nest, thus technically forming ...
Aluminum honeycomb structure Honeycomb structure in nature. Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all ...
7). ∪ ∪ ∪ = + = dual of . The A * 7 lattice (also called A 8 7) is the union of eight A 7 lattices, and has the vertex arrangement to the dual honeycomb of the omnitruncated 7-simplex honeycomb, and therefore the Voronoi cell of this lattice is an omnitruncated 7-simplex. ∪ ∪ ∪ ∪ ∪ ∪ ∪ = dual of .
Cubic honeycomb. In geometry, a honeycomb is a space filling or close packing of polyhedral or higher-dimensional cells, so that there are no gaps. It is an example of the more general mathematical tiling or tessellation in any number of dimensions. Its dimension can be clarified as n-honeycomb for a honeycomb of n-dimensional space.
Micrographia: or Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses. With Observations and Inquiries Thereupon is a historically significant book by Robert Hooke about his observations through various lenses. It was the first book to include illustrations of insects and plants as seen through microscopes.
