Some of the mathematical representation on [[Knuth's up-arrow notation]] is broken. There is too much whitespace.
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...
