Try this - the main macro is taken fron TTN but I modified it to overlay a
circle with an upsidedown ampersand. I have altered it for you, but haven't
checked this, so cross your fingers!

\makeatletter
\def\overlay#1#2{\mathpalette\@overlay{{#1}{#2}{\hfil}{\hfil}}}
\def\@overlay#1#2{\@@overlay#1#2}
\def\@@overlay#1#2#3#4#5{{%
\def\overlaystyle{#1}%
\setbox0=\hbox{\m@th$\overlaystyle#2$}%
\setbox1=\hbox{\m@th$\overlaystyle#3$}%
\ifdim \wd0<\wd1 \setbox2=\box1 \setbox1=\box0 \setbox0=\box2\fi
\rlap{\hbox to\wd0{#4\box1\relax#5}}\box0%
}}
\makeatother
\renewcommand{\Treturn}{{\overlay{Y}{\bigcirc}}}

Hi,

I've searched through the only LaTeX book our lab owns (A Guide to LaTeX by
Kopka and Daly--it really sucks so don't bother buying it) but can't find an

answer to this question. I need to superimpose two math symbols (namely, the
\bigcircle and Y to make a Turing machine return state symbol). Is there a way
to do this without using TeX commands? Actually, I'll take ANYTHING, even TeX
commands. Thanks for the help.

-Jonathan

now, that's peculiar. I've got quite a selection of LaTeX books in my
office, but that's the one people tend to run off with.

Try

\def\circleX#1{{\bigcirc\kern-.8em\raise -.1em\hbox{\rm\footnotesize #1}}}

Now, why should we help anyone with such an attitude problem? There are
at least two methods given in K&D.

Finally remembers some semblance of politesse. Perhaps there's hope.
