Hello, everyone. I'm posting this question to find out whether
the peculiarity of TeX which I ran into this morning is a well known
phenomenon.
Consider the expressions ${A_B}_C$ and ${\tilde A}_B$. They pose
no problems for TeX. However, TeX refuses to process the expression
${{\tilde A}_B}_C$,
claiming that there is a ``double subscript.'' The only workaround
for this that I know is to embed the $\tilde A$ in a \hbox.
Presumably, this behavior is explained by the rules in Appendix G
of the TeXbook; even so, I find it a bit illogical.
Am I doing something wrong? Is my difficulty familiar to everybody?
