LaTeX trick: rising diagonal dots

Just in case you ever need it: \ddots going the other direction:

\makeatletter
\def\Ddots{\mathinner{\mkern1mu\raise\p@
\vbox{\kern7\p@\hbox{.}}\mkern2mu
\raise4\p@\hbox{.}\mkern2mu\raise7\p@\hbox{.}\mkern1mu}}
\makeatother

Then you can say: \varepsilon_0= \omega^{\omega^{\Ddots}}

Or alternatively, download the package mathdots, which defines a command \iddots … which now I check doesn’t seem to be mentioned on LaTeX for Logicians.
