truncated cuboctahedron en · NOUN

Etymology

From truncated + cuboctahedron, referring to a partial construction (the resultant figure needs further distortion to make the faces regular).

Meanings

1. An Archimedean solid that is isogonal and has twenty-six regular faces (twelve square, eight hexagonal and six octagonal); a great rhombicuboctahedron.
   • 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. 1962, The Mineralogical Magazine and Journal of the Mineralogical Society, volume 33, page 1013:
   • 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. 2013, István Palinkó, Zoltán Kónya, Ákos Kukovecz, Imre Kiricsi, “22: Zeolites”, in Robert Vajtai, editor, Springer Handbook of Nanomaterials, page 822:
   • 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. 2012, Lesley E. Smart, Elaine A. Moore, Solid State Chemistry: An Introduction, 4th edition, page 274:
