Talk:Polyhedron/Archive 1

message: This article seems too dense, certainly initially. Regular polyhedron redirects here. I came looking for a place to redirect both regular solid and five regular solids; but the article as it stands would not be very helpful to the general reader needing those.

replies: text: I created a new subsection Regular polyhedra.  I think Regular polyhedron can redirect there.  (Regular polyhedra consists of 5 Platonic solids and 4 Kepler-Poinsot solids.)  --Perfecto 07:13, 9 September 2005 (UTC)
thread_title: Technical level

message: There. I've given the Classical section a major rewrite, hereby classifying all 75 uniform polyhedra.  Most of the subsections should now be candidates to be stubs of new articles.  The version I began with has several random musings.  Uniform Polyhedra should be clear of those now, and should be easier to read than Mathworld. --Perfecto 07:07, 9 September 2005 (UTC)
thread_title:  Classical polyhedron and Uniform polyhedra  

message: This section currently says there are 13 such forms, and lists 14 of them -- but I count 15 in Wenninger (67, 68, 70, 73, 78, 80, 87, 89, 90, 91, 94, 100, 102, 106, 107; Coxeter # 36, 37, 39, 45, 51, 53, 61, 63, 64, 65, 70, 78, 81, 85, 86).  Since the nomenclature differs I can't tell which one is missing, or have I goofed?  —Anton Sherwood 19:57, 11 January 2006 (UTC)
replies: text: Yes, W90 isn't quasiregular, but vertex figure looks correct - not symmetric. :Image:Small dodecicosahedron vertfig.png. There a few of these weird ones (W74, W99, W101, W103, W109), vertex configurations go two steps forward, two steps back, ending with a figure-8 vertex figure polygon of ambiguous radius as computable by the vertex face arrangements alone.

replies: text:  Yes, that's how the vf of W90 ought to look, a skew bowtie like those others you cite; but Wenninger shows it with four-way symmetry.  (Perhaps it is corrected in later printings; I bought my copy in 1981 at the very latest, probably before 1976.)  —Anton Sherwood 00:38, 13 January 2006 (UTC)
replies: text:  WOW! You're right. My book is wrong too (reprinted 1996!) I'll have to tape in a corrected image on the page! Another demonstration that independent generation is valuable! (Of course I never cross-compared my vertex figures systematically to the book diagrams, just figured they can't be wrong if mine actually generate the correct polyhedron!)

thread_title:  Non-convex quasi-regular polyhedra 

message: Hi all, I've just created a new article List of uniform polyhedra by vertex figure
which shows some relations amoung the uniform polyherdron. It seems a slightly more systematic
preseentation to me.
I've also created and infobox Template:Polyhedron types which shows the 
different classes of polyhedron. We could posibly uses this on other pages as a navigation aid.

thread_title: New article and template

message: The NL article linked -- nl:Afgeknotte hexa-octaëder -- appears to be much more specific than this.  Why is it linked?  —Tamfang 20:17, 1 February 2006 (UTC)

What is the name of the geometric solid that is the new pill bottle used by Target Pharmacy?...
