Alternated Hypercubic Honeycomb
In geometry, the alternated hypercube honeycomb (or demicubic honeycomb) is a dimensional infinite series of Honeycomb (geometry), honeycombs, based on the hypercube honeycomb with an Alternation (geometry), alternation operation. It is given a Schläfli symbol h representing the regular form with half the vertices removed and containing the symmetry of Coxeter diagram#Infinite Coxeter groups, Coxeter group _ for n ≥ 4. A lower symmetry form _ can be created by removing another mirror on an order-4 Peak (geometry), peak.Regular and semi-regular polytopes III, p.318-319 The alternated hypercube facets become demihypercubes, and the deleted vertices create new orthoplex facets. The vertex figure for honeycombs of this family are Rectification (geometry), rectified orthoplexes. These are also named as hδn for an (n-1)-dimensional honeycomb.

Uniform Tiling 44-t1
A uniform is a variety of clothing worn by members of an organization while participating in that organization's activity. Modern uniforms are most often worn by armed forces and paramilitary organizations such as police, emergency services, security guards, in some workplaces and schools and by inmates in prisons. In some countries, some other officials also wear uniforms in their duties; such is the case of the Commissioned Corps of the United States Public Health Service or the French prefects. For some organizations, such as police, it may be illegal for non members to wear the uniform. Etymology From the Latin ''unus'', one, and ''forma'', form. Corporate and work uniforms Workers sometimes wear uniforms or corporate clothing of one nature or another. Workers required to wear a uniform may include retail workers, bank and post-office workers, public-security and health-care workers, blue-collar employees, personal trainers in health clubs, instructors in summer cam ...
