Hi,
Some of the mathematical representation on [[Knuth's up-arrow notation]] is broken. There is too much whitespace. See:
http://en.wikipedia.org/math/a62fcfaa06f5fa6052ab4b8bf292f7fd.png
I don't know what causes this, but it doesn't look nice.
kind regards, Gerrit.

Have you tried removing some of the quad-spaces? The terms are arranged like this (pardon my ASCII art):
XYZ ... = ----- = ... ______ABC_bizbax
where the _ here represents literal spaces in. Presumably this is meant to align things just so, but it creates, well, a bunch of whitespace.

Yes, I think this is just a good example of abusing layout syntax - your use of ASCII art is to the point. Rather than using a table with multiple columns, somebody has used a table with 2 rows but 1 column, and put a lot of spaces in so that the text on the bottom lines up with a particular part above it. I'm going to try and fix things up now. [Not that I have any experience with TeX, this just seems to "make sense"]

Right, I've fixed most of the formulae to make proper use of \matrix as a table, rather than just using whitespace to line things up on each row. Hopefully, this will look good more reliably.
The only one I couldn't make work was the 3-row one just after the text "...an n-arrow operator expands into a series of (n − 1)-arrow operators. Symbolically..." (which doesn't look dodgy, but is just 3 rows full of whitespace). I can't find a way (if there is one) of spanning multiple columns inside a \matrix{}, or of making the underbrace extend across text in different "table cells". Still, I guess if it looks OK for now, it will stay looking OK unless someone edits it...
