Hopf spherical coordinates
This section introduces the Hopf coordinates and gives the rationale for using them to describe 4-polytopes, and some references, but no further use is made of this kind of coordinates elsewhere in the article. The section gives the Hopf coordinates for the $$H_4$$ polytopes, explaining that these are the coordinates of the whole 600-point 120-cell, but the specific Hopf coordinates of the 120-point 600-cell that is the subject of this article are not identified. Elsewhere throughout the article some use is made of Cartesian coordinates, but Hopf coordinates are not given, and currently they are never mentioned again. Please improve this article by using Hopf coordinates to illustrate features of the 600-cell. Dc.samizdat (discuss • contribs) 16:20, 19 May 2024 (UTC)
