Talk:Compound of four tetrahedra

another not covered
The figure linked at Geogebra looks like what I get by rotating a tet by &pi;/3 about each altitude line. —Tamfang (talk) 21:50, 26 January 2023 (UTC)

Image for compound of four dyadic or digonal antiprisms
I'll be uploading a different image from Stella in a day or two. Radlrb (talk) 08:09, 27 January 2023 (UTC)

So that's a wonderful image JeffUK, thank you for producing it! Is there any way you could make the background white? Again, I appreciate your help with the article. Radlrb (talk) 21:53, 27 January 2023 (UTC)


 * For some reason, it wanted to be grey! I will see if I can convince it otherwise. Jeff UK  22:34, 27 January 2023 (UTC)
 * There you go! Background is white; colours more bold, and less shiny. Jeff UK 22:46, 27 January 2023 (UTC)


 * Lovely lovely lovely ah so nice gracias Jeff! Radlrb (talk) 00:59, 28 January 2023 (UTC)
 * Okay, this is actually not a well known polyhedron, except in small circles. As the already magnificent piece it is, it should be featured in my humble opinion. Can you give it proper referencing if need be? If you used Stella, or otherwise, and get a proper approval (again, if need be, and for email verification, etc.). If it is entirely yours from a program that is generic other than Stella like GeoGebra or otherwise (which can be added I think, ?). Because, you know, this thing rotating is !

surface area

 * This compound has a surface area equal to:

Please specify a unit. Edge length is the obvious assumption, but Coxeter (iirc) liked to use half-edges. —Tamfang (talk) 18:55, 27 January 2023 (UTC)


 * Yes, I had forgotten to specify, would have caught it by the end of the afternoon, ty. Radlrb (talk) 19:47, 27 January 2023 (UTC)
 * I edited over again the improvement you made on the surface area. I think it's okay now. We have a rotating image too, I'm sure you noticed.
