Nice article! I didn't understand this:
- (2) The nimber square of a Fermat 2-power x is equal to the standard value of 3x/2.
What does "standard value of 3x/2" mean? AxelBoldt 01:50 Jan 5, 2003 (UTC)
Thanks. The part that you asked about has been edited. It means the value of 3x/2 under the ordinary multiplication of natural numbers, so that the nimber square of 2 is 3, the nimber square of 4 is 6, the nimber square of 16 is 24, the nimber square of 256 is 384, etc. David McAnally 21:22 Jul 1, 2004 (AEST)
Other than the clumsy workaround 22^n or some sort of graphic (such as appears on the Fermat number page), is there any way to get Wikipedia to deal with nested exponents? I changed to the above workaround, as the previous format looked like 22n in my browser. MJSS 20:29, 3 Sep 2004 (UTC)
- If worse comes to worst you could resort to TeX and write: <math>2^{2^n}<math>. Formerly, TeX looked good when "displayed" and often looked terrible when embedded in lines of text. Now it may look less than beautiful, but usually is nowhere near as bad as it used to be. Of course, if you're going to "display" it, thus
- <math>\int_0^\infty 1\,dx<math>
- then using TeX works well. Michael Hardy 22:17, 3 Sep 2004 (UTC)
- Oh -- one more thing. The paragraph I wrote above was already indented, so I need to indent the "displayed" TeX twice. Michael Hardy 22:18, 3 Sep 2004 (UTC)
There is a similar problem with omega^omrga^omega at the point where it was pointed out that the set of nimbers less than omega^omega^omega is an algebraically closed field. Like 2^2^n, it does not look right, although it once did.

What does the following look like to you?
- <math>\omega^{\omega^\omega}\neq 2^{2^n}.<math>
Specifically where in the article is the problem you're referring to?
