[edit] Trivia
If each edge of a cube is replaced by a one ohm resistor, the resistance between opposite vertices is 5/6 ohms, and that between adjacent vertices 7/12 ohms.
...Above text was deleted by IP user. I copied it here rather than reverting or allowing it to be lost in case anyone cares. Tom Ruen 09:25, 10 January 2006 (UTC)
[edit] New stat table
I replace stat table with template version, which uses tricky nested templates as a "database" which allows the same data to be reformatted into multiple locations and formats. See here for more details: User:Tomruen/polyhedron_db_testing

[edit] added face/facet/side
to clarify meaning. 0waldo 02:12, 17 May 2006 (UTC)

[edit] Equation
The equation for a cube is 
, where s is the length of a side. Is this worth mentioning? If no one objects, I will add it. ForrestVoight 15:06, 13 June 2006 (UTC)
- Are you sure that's a cube and not an octahedron? -- Jitse Niesen (talk) 13:31, 13 June 2006 (UTC)
- For a cube, try max(|x|, |y|, |z|) = s/2, instead. -- The Anome 13:37, 13 June 2006 (UTC)
Oops, thats an octahedron. Do you think it should go on the octahedron page? ForrestVoight 15:06, 13 June 2006 (UTC)
- Yes, go ahead. Cube, Sphere and Octahedron could each have a brief passage comparing the ∞-norm (measure polytope), 2-norm (sphere) and 1-norm (cross polytope). —Tamfang 17:32, 13 June 2006 (UTC)

- That's an excellent idea. -- The Anome 21:28, 14 June 2006 (UTC)
- I've added three sentences to Norm (mathematics). —Tamfang 22:15, 14 June 2006 (UTC)
[edit] those idiot redirections
are apparently part of a long pattern, see Wikipedia:Long term abuse/Videogamer. —Tamfang 05:21, 25 August 2006 (UTC)
[edit] Hypercubes
We need some terminology cleaned up. The name measure polytope is rare at best. I have changed it to hypercube and "n-cube". There is a move being considered of the page "measure polytope" to "hypercube" (see their talk pages). Zaslav 02:02, 16 November 2006 (UTC)
[edit] "Combinatorial cubes"
I replaced this, which was incomprehensibly vague, by a brief description of the cube graph and the 3-dimensional Hamming graph. A full discussion of either one appears in separate articles, hypercube graph and Hamming graph. If the person who wanted to describe k-ary n-cubes wishes to write a readable article, it should appear under that title (but first check to see if it's different from a Hamming graph).

[edit] Request: Internal angles
An IP editor left the following request in the article: "Could someone please add the internal angles within a cube. I am particularly interested in the angles of the internal diagonal. Thank you." -- Jitse Niesen (talk) 10:40, 5 January 2007 (UTC)
