[texhax] symbol for triple vertical 'x'

[tom sgouros]

You could try this:

\newcommand{\recur}{\hbox to 1ex{\hbox to0pt{\raisebox{0.7ex}{x}}%
\hbox to0pt{\raisebox{-0.5ex}{x}}%
\hbox to0pt{\raisebox{0.1ex}{x}}}}

Probably there's a tidier way, but this answers part of your request.
I also imagine someone else here can explain why the % signs are
necessary, but they are.
