[[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. —[[User:Tamfang|Tamfang]] ([[User talk:Tamfang|talk]]) 19:34, 3 February 2011 (UTC)

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.

== 30-tetrahedron rings are duals of [[Petrie polygon|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.)
