Talk:Cuboctahedron

message: It would be fun to add a section Cuboctahedra in the arts, if anyone can remember which episode of Old Star Trek had the badguys zap some of the crew into the form of little plaster cubocs.  --Anton Sherwood 01:33, 13 January 2006 (UTC)

message: User:Ptah changed
:A = (6+2\sqrt{3})a^2 \approx 9.46410162a^2
to
:A = (6+4\sqrt{3})a^2 \approx 12.92820323a^2
Eight triangles of unit base and height √3/2 gives 8*√3/4 = 2√3, not 4√3.  Have I missed something?  —Tamfang (talk) 08:23, 22 January 2008 (UTC)

message: User:KoenDelaere changed the vertex coordinates to
: (±√2,0,0)
: (0,±√2,0)
: (±1/√2,±1/√2,±1) 
User:Tomruen reverted to (±1,±1,0) and its permutations, which are preferred because they're more symmetric; but I'd like to mention for the record that KoenDelaere's version is not wrong – it's an eighth-rotation in (x,y). —Tamfang (talk) 01:57, 1 March 2010 (UTC)

message: The table at the top right of the article ought, I think, to give its Schläfli symbol as \begin{Bmatrix} 3 \\ 4 \end{Bmatrix} , by analogy with icosidodecahedron. I would change it, but I can't figure out how to get at the table for editing purposes. Maproom (talk) 12:32, 27 January 2011 (UTC)
replies: text: There's different notations, see Uniform_polyhedron#Wythoff_construction_operators. They should be consistent in the tables, so I changed it. Tom Ruen (talk) 19:51, 27 January 2011 (UTC)

message: Amazingly, the cuboctahedron (and a few other recognizable geometric shapes, but mostly cuboctahedra) is the shape taken by "COPII" proteins when they are transported from the "endoplasmic reticulum" to the "golgi apparatus" http://www.nature.com/nrm/journal/v7/n10/images/nrm2025-f2.jpg  — Preceding unsigned comment added by 129.215.109.69 (talk) 12:58, 18 September 2015 (UTC)

message: (This is the bad section)
The cuboctahedron can be dissected into 6 square pyramids and 8 tetrahedra meeting at a central point. This dissection is expressed in the tetrahedral-octahedral honeycomb where pairs of square pyramids are combined into octahedra. Glenneric1 (talk) 13:10, 27 March 2023 (UTC)
replies: text: It's a square dipyramid, dissected into cells of the lattice mentioned in the second sentence.  A picture of a dissected CO would still be good. —Tamfang (talk) 05:51, 5 April 2023 (UTC)
thread_title:  Correction to "Dissection" section, object shown is a square pyramid, not cuboctahedron
