Cyclic Permutation

Two things, the article for cyclic permutation has 3 definitions (and a poor description of each) so it is difficult to know exactly what this article means by cyclic permutation since it defers to that article. Second, there are two given coordinates with several "plus or minus" in them. This makes it doubly difficult to understand what is meant I think. I would suggest that somebody who understands what this means just list out all 30 coordinates or at least explain better how to derive them from the rather terse description. -- User:74.192.27.195, 22:33, April 4, 2011.

Picture

This article would be much better with a picture. Any takers? Theresa knott 12:03 23 Jun 2003 (UTC)

Well, I guess I might consider the possibility of creating a picture, some time... كسيپ Cyp 14:24 23 Jun 2003 (UTC)

It's beutiful! Theresa knott 14:54 23 Jun 2003 (UTC)

Should we use the svg or the jpg? Here's a comparison.

I prefer the jpg, but have no objections against changing to svg. Professor M. Fiendish 05:14, 23 August 2009 (UTC)[reply]

Pronunciation Key?

Maybe we should add a pronunciation key of some sort? Is it pronounced Iso-side-o-decahedron?

I think it's icosidodecahedron with a hard "c" and a short second "i". (The first "i" is probably pronounced as in "iso-".) Professor M. Fiendish 05:11, 23 August 2009 (UTC)[reply]

I think it's i-KO-see-doh-DEK-a-HEE-dron, either with a long or short O in the second syllable. But definitely the "icosi" part is separate from the "dodeca" part. —The Doctahedron, 68.173.113.106 (talk) 22:07, 22 November 2011 (UTC)[reply]

Use in first nuclear designs?

Should it be mentioned this was the shape of the Trinity Test Design of nuclear device? —Preceding unsigned comment added by 99.1.35.250 (talk) 17:44, 30 January 2009 (UTC)[reply]

Sounds interesting if you have references. I've not seen that. Tom Ruen (talk) 23:54, 30 January 2009 (UTC)[reply]

The same claim is already made on the Truncated_icosahedron#Applications article. Tom Ruen (talk) 23:59, 30 January 2009 (UTC)[reply]

Ah thanks, I had seen the Opera Doctor Atomic and in the libretto they described it a dodecahedron inscribed by a icosahedron with 32 vertices equidistance from the center of the shape. That is just a truncated icosahedron then —Preceding unsigned comment added by 99.1.35.250 (talk) 00:45, 31 January 2009 (UTC)[reply]

If it has 32 vertices, it might be the dual of the truncated icosahedron: Pentakis_dodecahedron. Tom Ruen (talk) 23:34, 31 January 2009 (UTC)[reply]

That is the shape. I checked the libretto again and it matches exactly the numerical data of that shape. I edited it and included a source of the libretto. —Preceding unsigned comment added by 99.1.35.250 (talk) 00:03, 2 February 2009 (UTC)[reply]

Icosadodecahedron

Icosadodecahedron redirects here. Is this a pure synonym for Icosidodecahedron? --Abdull (talk) 21:40, 9 July 2010 (UTC)[reply]

Probably a common misspelling. Why, did you find another meaning of the term?—Tetracube (talk) 03:20, 10 July 2010 (UTC)[reply]
