Talk:Boerdijk–Coxeter helix

Start
I know it's not much of a page yet, but i expect some help on it soon, and i promised i'd make a start for it. Any help is appreciated.

strange insertions
has several times inserted weird sentences:
 * "Tetrahedra are unilaterally cosined against the heraclitean plane" (30 Aug 2009)
 * "London dispersion forces are colineally arranged in a boolean triagram to offset the isomeric aspect." (26 Aug 2010)
 * "The Helices are counter isomeric to the interchange of electron flow." (17 Jan 2011)
 * "The synergistic intertwining of the lateral helices are cosined against the perpendicular axial stack." (2 Feb 2011)

London dispersion force at least is a real concept, so I hesitated to assume that it's junk; but now that I've listed these all together I see that no two of these insertions have anything in common (except "cosined against"), so it's implausible that they have any serious intent. —Tamfang (talk) 19:34, 3 February 2011 (UTC)

citations?
Dear Wikipedia guys,

This page contains an interesting claim that appears on the 600-cell page as well, namely that the 600-cell decomposes into a union of 20 solid tori each with a triangulation that locally looks like this helix formed of tetrahedra in such a way that there is a simplicial map to the boundary complex of the icosahedron such that the each solid torus maps to a face and the fiber over each vertex is a Hopf circle. The usual procedure when publishing such a claim is to provide a citation to literature that gives a proof or at least a claim of a proof as in a research announcement.

Perhaps I'm not searching carefully enough, but I do not see such a proof in any of the cited literature on this page. The scholarly value of the article would be improved considerably if such a citation were present. 123.116.217.128 (talk) 14:56, 1 September 2015 (UTC)

30-tetrahedron rings are duals of Petrie polygons
The 600-cell partitions into 20 rings of 30 tetrahedra (see article). I noticed that the duals of these rings are Petrie polygons of the 120-cell. Thus, the vertex set of the 120-cell partitions into 20 Petrie polygons. (I discovered this partition of the vertex set 20 years ago, but there is no publication.)
