Web pages for infinitely iterated exponentials
Dave L. Renfro
that I wanted to archived at sci.math for something I'm working on.
Also, since this topic comes up fairly often in sci.math, the
archived-URL for this post can be used to quickly disseminate a
lot of information to newbies asking questions on this topic.
1. "Iterated Exponential Constants" at Steven Finch's "Favorite
Mathematical Constants" web page. [Some nice graphs along with 26
references. Has a 7 page Netscape Print Preview output.]
<http://pauillac.inria.fr/algo/bsolve/constant/itrexp/itrexp.html>
2. Ioannis Galidakis's "Infinite Exponentials" and "A slightly
deeper analysis". [These have 9 and 11 page Netscape Print
Preview outputs, respectively.]

3. Joseph MacDonnell's "Some Critical Points of the Hyperpower
Function y = x^x^x^..." [Has a 7 page Netscape Print Preview
output.]
<http://www.faculty.fairfield.edu/jmac/ther/tower.htm>
4. Louis A. Talman's "On x^x^x..." [Click on 'For what real x does
the "continued exponential" x^(x^(x^(x^...)))'. 464K .pdf,
19K .dvi, and 79K .ps files available. The .ps file generates a
5 page output.]

5. This web page gives what appears to be a paradox involving the
equation x^(x^(x^(...))) = 2.
