| In [[geometry]], the '''truncated cuboctahedron''' is an [[Archimedean solid]]. It has 12 [[Square (geometry)|square]] faces, 8 regular [[hexagon]]al faces, 6 regular [[octagon]]al faces, 48 vertices and 72 edges. Since each of its faces has [[point symmetry]] (equivalently, 180° [[rotation]]al symmetry), the truncated cuboctahedron is a [[zonohedron]].
| |
| | |
| ==Cartesian coordinates==
| |
| The [[Cartesian coordinates]] for the vertices of a truncated cuboctahedron having edge length 2 and centered at the origin are all [[permutation]]s of:
| |
| :(±1, ±(1+√2), ±(1+2√2))
| |
| | |
| ==Area and volume==
| |
| The area ''A'' and the volume ''V'' of the truncated cuboctahedron of edge length ''a'' are:
| |
| :<math>A = 12\left(2+\sqrt{2}+\sqrt{3}\right) a^2 \approx 61.7551724a^2</math>
| |
| :<math>V = \left(22+14\sqrt{2}\right) a^3 \approx 41.7989899a^3.</math>
| |
| | |
| ==Vertices==
| |
| To derive the number of vertices, we note that each vertex is the meeting point of a square, hexagon, and octagon.
| |
| *Each of the 12 squares with their 4 vertices contribute 48 vertices because 12 × 4 = 48.
| |
| *Each of the 8 hexagons with their 6 vertices contribute 48 vertices because 8 × 6 = 48.
| |
| *Each of the 6 octagons with their 8 vertices contribute 48 vertices because 6 × 8 = 48.
| |
| | |
| Therefore, there may seem to exist {{nowrap|48 + 48 + 48 {{=}} 144}} vertices. However, we have over-counted the vertices thrice since a square, hexagon, and octagon meet at each vertex. Consequently, we divide 144 by 3 to correct for our over-counting: {{nowrap|144 / 3 {{=}} 48.}}
| |
| | |
| ==Dual==
| |
| If the original truncated cuboctahedron has edge length 1, its dual [[disdyakis dodecahedron]] has edge lengths <math>\tfrac{2}{7}\scriptstyle{\sqrt{30-3\sqrt{2}}}</math>, <math>\tfrac{3}{7}\scriptstyle{\sqrt{6(2+\sqrt{2})}}</math> and <math>\tfrac{2}{7}\scriptstyle{\sqrt{6(10+\sqrt{2})}}</math>.
| |
| | |
| ==Uniform colorings==
| |
| There is only one [[uniform coloring]] of the faces of this polyhedron, one color for each face type.
| |
| | |
| A 2-uniform coloring also exists with alternately colored hexagons.
| |
| | |
| ==Other names==
| |
| Alternate interchangeable names are:
| |
| *''Truncated cuboctahedron'' ([[Johannes Kepler]])
| |
| *''Rhombitruncated cuboctahedron'' ([[Magnus Wenninger]]<ref>{{Citation |last1=Wenninger |first1=Magnus |author1-link=Magnus Wenninger |title=Polyhedron Models |publisher=[[Cambridge University Press]] |isbn=978-0-521-09859-5 |id={{MathSciNet|id=0467493}} |year=1974}} (Model 15, p. 29)</ref>)
| |
| *''Great rhombicuboctahedron'' (Robert Williams<ref>{{The Geometrical Foundation of Natural Structure (book)}} (Section 3-9, p. 82)</ref>)
| |
| *''Great rhombcuboctahedron'' (Peter Cromwell<ref>Cromwell, P.; [http://books.google.com/books?id=OJowej1QWpoC&lpg=PP1&pg=PA82#v=onepage&q=&f=false ''Polyhedra''], CUP hbk (1997), pbk. (1999). (p. 82) </ref>)
| |
| *''Omnitruncated cube'' or ''cantitruncated cube'' ([[Norman Johnson (mathematician)|Norman Johnson]])
| |
| | |
| The name ''truncated cuboctahedron'', given originally by [[Johannes Kepler]], is a little misleading. If you [[truncation (geometry)|truncate]] a [[cuboctahedron]] by cutting the corners off, you do ''not'' get this uniform figure: some of the faces will be [[rectangle]]s. However, the resulting figure is [[topologically]] equivalent to a truncated cuboctahedron and can always be deformed until the faces are regular.
| |
| | |
| The alternative name ''great rhombicuboctahedron'' refers to the fact that the 12 square faces lie in the same planes as the 12 faces of the [[rhombic dodecahedron]] which is dual to the cuboctahedron. Compare to [[small rhombicuboctahedron]].
| |
| | |
| One unfortunate point of confusion: There is a [[nonconvex uniform polyhedron]] by the same name. See [[nonconvex great rhombicuboctahedron]].
| |
| ==Orthogonal projections==
| |
| The truncated cuboctahedron has two special [[orthogonal projection]]s in the A<sub>2</sub> and B<sub>2</sub> [[Coxeter plane]]s with [6] and [8] projective symmetry, and numerous [2] symmtries can be constructed from various projected planes relative to the polyhedron elements.

| == Related polyhedra==
| |
| The truncated cuboctahedron is one of a family of uniform polyhedra related to the cube and regular octahedron.
| |
| | |
| {{Octahedral truncations}}
| |
| | |
| This polyhedron can be considered a member of a sequence of uniform patterns with vertex figure (4.6.2p) and [[Coxeter-Dynkin diagram]] {{CDD|node_1|p|node_1|3|node_1}}. For ''p'' < 6, the members of the sequence are [[Omnitruncation (geometry)|omnitruncated]] polyhedra ([[zonohedron]]s), shown below as spherical tilings. For ''p'' > 6, they are tilings of the hyperbolic plane, starting with the [[truncated triheptagonal tiling]].
