Etymology
[edit]From truncated + cuboctahedron, referring to a partial construction (the resultant figure needs further distortion to make the faces regular).
Noun
[edit]truncated cuboctahedron (plural truncated cuboctahedra or truncated cuboctahedrons)
- (geometry) An Archimedean solid that is isogonal and has twenty-six regular faces (twelve square, eight hexagonal and six octagonal); a great rhombicuboctahedron.
- 1962, The Mineralogical Magazine and Journal of the Mineralogical Society, volume 33, page 1013:
- The H'(S-S) type of linked truncated octahedra and truncated cuboctahedra is analogous to the fluorite structure with the truncated octahedra in the positions of the fluorine atoms and the truncated cuboctahedra in the positions of the calcium atoms.
- 2012, Lesley E. Smart, Elaine A. Moore, Solid State Chemistry: An Introduction, 4th edition, page 274:
- A three-dimensional network of linked cavities, each with a truncated cuboctahedron shape (Figure 6.5) through the structure, is thus formed; the truncated cuboctahedra are also space-filling (each shares its octagonal face with six others), forming channels that run parallel to the three axial cubic directions through these large cavities.
- 2013, István Palinkó, Zoltán Kónya, Ákos Kukovecz, Imre Kiricsi, “22: Zeolites”, in Robert Vajtai, editor, Springer Handbook of Nanomaterials, page 822:
- Its pore structure consists of truncated octahedra linked to other cavities through 6-membered rings and of truncated cuboctahedra linked together through 8-membered rings.
Usage notes
[edit]The term is considered by some to be "improper" or misleading, because truncation of an octahedron yields a form with irregular faces that must be further distorted.
