Talk:Enneahedron

Why "ambiguous"?
In what sense is the term enneahedron (or nonahedron) "ambiguous"? Yes, there are many different arrangements of edges and vertices included in the definition, but that is not ambiguous -- just a name which covers a large (and possibly confusing) set of mathematical objects with little in common save their having 9 faces..

Edit warring re name
An anonymous editor has been repeatedly trying to move this page to Nonahedron, and has been doing it both without any discussion and consensus here, and also doing it the wrong way (copying and pasting into the new name rather than a history-preserving move). I have semiprotected the page so that we can discuss the issue here without this disruption. Please discuss whether this move is appropriate rather than continuing to edit war. I may also weigh in myself later, but have not yet formulated an opinion on which is the better name. —David Eppstein (talk) 07:27, 17 November 2016 (UTC)
 * I think nonagon is assuredly the right place for the polygon, since there the Latin-Greek portmanteau is more common. I do not think nonahedron is the right place for the set of polyhedra. They are not referred to as such very often (because it's a very unspecific name) and both terms get about the same number of hits on Google Scholar (nonahedra, enneahedra). When we consider higher polygons and polyhedra where 9 is one of the digits, e.g. enneadecagon and rhombic enneacontahedron, we find that ennea- (the Greek form) is very common and nona- is near nonexistent. Apart from the exception nonagon, then, due to its clearly superior popularity, I therefore do not favour breaking consistency. Double sharp (talk) 07:35, 17 November 2016 (UTC)

"None of them are regular." is grammatically wrong. None is a contraction of not one, and therefore takes a singular verb. It should read "None of them is regular". 86.151.115.83 (talk) 09:20, 12 June 2020 (UTC)


 * ❌. Nope, none can take both the singular or plural depending on the situation. In this case, plural is correct and probably more natural-sounding. –Deacon Vorbis (carbon &bull; videos) 13:31, 12 June 2020 (UTC)
