Yes, I'd forgotten that. I was just trying to work out how I'd do that in LaTeX, and the best I could come up with was ================================ \documentclass[12pt]{article} \usepackage{amsmath} \usepackage[russian]{babel} \newcommand{\shaf}{\operatorname{\text{\CYRSH}}} \begin{document} The group $\shaf$. \end{document} ================================ As a matter of interest, what would be the kosher way to do this? But my serious point is that it seems to me more sensible to use a macro-name like \shaf rather than arranging for a single input character to create this output. -- Timothy Murphy e-mail: [log in to unmask] tel: +353-86-233 6090 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
