In [[geometry]], a '''convex uniform honeycomb''' is a uniform space-filling [[tessellation]] in three-dimensional [[Euclidean space]] with non-overlapping convex [[uniform polyhedron|uniform polyhedral]] cells.
Twenty-eight such honeycombs exist:
* the familiar [[Convex uniform honeycomb#The_R4.2C_.5B4.2C3.2C4.5D_group_.28cubic.29|cubic honeycomb]] and 7 truncations thereof;
* the [[Convex uniform honeycomb#Alternated cubic forms|alternated cubic honeycomb]] and 4 truncations thereof;
* 10 prismatic forms based on the [[Convex uniform honeycomb#Stacked prismatic forms|uniform plane tilings]] (11 if including the cubic honeycomb);
* 5 modifications of some of the above by elongation and/or gyration.
They can be considered the three-dimensional analogue to the [[List of uniform planar tilings|uniform tilings of the plane]].
== History ==
* '''1900''': [[Thorold Gosset]] enumerated the list of semiregular convex polytopes with regular cells ([[Platonic solid]]s) in his publication ''On the Regular and Semi-Regular Figures in Space of n Dimensions'', including one regular cubic honeycomb, and two semiregular forms with tetrahedra and octahedra.
* '''1905''': [[Alfredo Andreini]] enumerated 25 of these tessellations.
* '''1991''': [[Norman Johnson (mathematician)|Norman Johnson]]'s manuscript ''Uniform Polytopes'' identified the complete list of 28.
* '''1994''': [[Branko Grünbaum]], in his paper ''Uniform tilings of 3-space'', also independently enumerated all 28, after discovering errors in Andreini's publication. He found the 1905 paper, which listed 25, had 1 wrong, and [[Convex uniform honeycomb#Gyrated and elongated forms|4 being missing]]. Grünbaum also states that [[I. Alexeyev]] of Russia also independently enumerated these forms around the same time.
* '''2006''': [[George Olshevsky]], in his manuscript ''Uniform Panoploid Tetracombs'', along with repeating the derived list of 11 convex uniform tilings, and 28 convex uniform honeycombs, expands a further derived list of 143 convex uniform tetracombs (Honeycombs of [[uniform polychoron]]s in 4-space).
Only 14 of the convex uniform polyhedra appear in these patterns:
* three of the five [[Platonic solid]]s,
* six of the thirteen [[Archimedean solid]]s, and
* five of the infinite family of [[prism (geometry)|prism]]s.
=== Names ===
This set can be called the '''regular and semiregular honeycombs'''. It has been called the '''Archimedean honeycombs''' by analogy with the convex uniform (non-regular) polyhedra, commonly called [[Archimedean solid]]s. Recently [[John Horton Conway|Conway]] has suggested naming the set as the '''Architectonic tessellations''' and the dual honeycombs as the '''Catoptric tessellations'''.
The individual honeycombs are listed with names given to them by [[Norman Johnson]]. (Some of the terms used below are defined in [[Uniform polychoron#Geometric derivations]].)
For cross-referencing, they are given with list indices from [A]ndreini (1-22), [W]illiams(1-2,9-19), [J]ohnson (11-19, 21-25, 31-34, 41-49, 51-52, 61-65), and [G]runbaum(1-28).
== Tessellations listed by infinite Coxeter group families ==
[[Image:Coxeter-Dynkin 3-space groups.png|400px|thumb|Fundamental domains in a cubic element of three groups.]]
The fundamental infinite [[Coxeter group]]s for 3-space are:
# The R<sub>4</sub>, [4,3,4], cubic, [[Image:CDW_dot.png]][[Image:CDW_4.png]][[Image:CDW_dot.png]][[Image:CDW_3.png]][[Image:CDW_dot.png]][[Image:CDW_4.png]][[Image:CDW_dot.png]] (8 unique forms plus one alternation)
# The S<sub>4</sub>, h[4,3,4], alternated cubic, [[Image:CD_dot.png]][[Image:CD_3b.png]][[Image:CD_downbranch-00.png]][[Image:CD_3b.png]][[Image:CD_4.png]][[Image:CD_dot.png]] (11 forms, 3 new)
# The P<sub>4</sub> cyclic group, [[Image:CD downbranch-00.png]][[Image:CD downbranch-33.png]][[Image:CD downbranch-00.png]] (5 forms, one new)
In addition there are 5 special honeycombs which don't have pure reflectional symmetry and are constructed from reflectional forms with ''elongation'' and ''gyration'' operations.
The total unique honeycombs above are 18.
The prismatic stacks from infinite Coxeter groups for 3-space are:
# The R<sub>3</sub>xW<sub>2</sub>, [4,4]x[∞] prismatic group, [[Image:CDW_dot.png]][[Image:CDW_4.png]][[Image:CDW_dot.png]][[Image:CDW_4.png]][[Image:CDW_dot.png]][[Image:CDW_2.png]][[Image:CDW_dot.png]][[Image:CDW_infin.png]][[Image:CDW_dot.png]] (2 new forms)
# The V<sub>3</sub>xW<sub>2</sub>, [6,3]x[∞] prismatic group, [[Image:CDW_dot.png]][[Image:CDW_6.png]][[Image:CDW_dot.png]][[Image:CDW_3.png]][[Image:CDW_dot.png]][[Image:CDW_2.png]][[Image:CDW_dot.png]][[Image:CDW_infin.png]][[Image:CDW_dot.png]] (7 unique forms)
# The P<sub>3</sub>xW<sub>2</sub>, [Δ]x[∞] prismatic group, [[Image:CD righttriangle-000.png]][[Image:CD_2.png]][[Image:CD_dot.png]][[Image:CD_infin.png]][[Image:CD_dot.png]] (No new forms)
# The W<sub>2</sub>xW<sub>2</sub>xW<sub>2</sub>, [∞]x[∞]x[∞] prismatic group, [[Image:CDW_dot.png]][[Image:CDW_infin.png]][[Image:CDW_dot.png]][[Image:CDW_2.png]][[Image:CDW_dot.png]][[Image:CDW_infin.png]][[Image:CDW_dot.png]][[Image:CDW_2.png]][[Image:CDW_dot.png]][[Image:CDW_infin.png]][[Image:CDW_dot.png]] (These all become a ''cubic honeycomb'')
In addition there is one special ''elongated'' form of the triangular prismatic honeycomb.
The total unique prismatic honeycombs above (excluding the cubic counted previously) are 10.
Combining these counts, 18 and 10 gives us the total 28 uniform honeycombs.
=== The R<sub>4</sub>, [4,3,4] group (cubic) ===
The regular cubic honeycomb, represented by Schläfli symbol {4,3,4}, offers seven unique derived uniform honeycombs via truncation operations. (One redundant form, the ''runcinated cubic honeycomb'', is included for completeness though identical to the cubic honeycomb.)

=== S<sub>4</sub>, h[4,3,4], [4,3<sup>1,1</sup>] group ===
The S<sub>4</sub> group offers 11 derived forms via truncation operations, four being unique uniform honeycombs.
The honeycombs from this group are called ''alternated cubic'' because the first form can be seen as a ''cubic honeycomb'' with alternate vertices cubic cells to tetrahedra, and creating octahedron cells in the deleted gaps.
Nodes are indexed left to right as ''0,1,0',3'' with 0' being below and interchangeable with ''0''. The ''alternate cubic'' names given are based on this ordering.

=== Gyrated and elongated forms ===
Three more uniform honeycombs are generated by breaking one or another of the above honeycombs where its faces form a continuous plane, then rotating alternate layers by 60 or 90 degrees (''gyration'') and/or inserting a layer of prisms (''elongation'').
The elongated and gyroelongated alternated cubic tilings have the same vertex figure, but are not alike. In the ''elongated'' form, each prism meets a tetrahedron at one triangular end and an octahedron at the other. In the ''gyroelongated'' form, prisms that meet tetrahedra at both ends alternate with prisms that meet octahedra at both ends.
The gyroelongated triangular prismatic tiling has the same vertex figure as one of the plain prismatic tilings; the two may be derived from the gyrated and plain triangular prismatic tilings, respectively, by inserting layers of cubes.

=== Prismatic stacks ===
Eleven '''prismatic''' tilings are obtained by stacking the eleven [[tiling by regular polygons|uniform plane tilings]], shown below, in parallel layers. (One of these honeycombs is the cubic, shown above.) The [[vertex figure]] of each is an irregular [[bipyramid]] whose faces are [[isosceles triangle]]s.
==== The R<sub>3</sub>xW<sub>2</sub>, [4,4] x [∞], prismatic group ====
There's only 3 unique honeycombs from the square tiling, but all 6 tiling truncations are listed below for completeness, and tiling images are shown by colors corresponding to each form.

==Examples==
All 28 of these tessellations are found in [[crystal]] arrangements.
The [[tetrahedral-octahedral honeycomb|alternated cubic honeycomb]] is of special importance since its vertices form a cubic [[close-packing]] of spheres. The space-filling [[truss]] of packed octahedra and tetrahedra was apparently first discovered by [[Alexander Graham Bell]] and independently re-discovered by [[Buckminster Fuller]] (who called it the [[octet truss]] and patented it in the 1940s).
[http://tabletoptelephone.com/~hopspage/Fuller.html]
[http://members.cruzio.com/~devarco/energy.htm]
[http://www.n55.dk/MANUALS/DISCUSSIONS/OTHER_TEXTS/CM_TEXT.html]
[http://www.cjfearnley.com/fuller-faq-2.html]. Octet trusses are now among the most common types of truss used in construction.
<!--
FIXME: move this discussion of octet truss to [[Buckminster Fuller]] or perhaps [[octet truss]], leaving behind a link to where it went.
