Here's a nice little teaser, André,
from the Lamport book, page 49
\[ \underbrace{a+\overbrace{b+\cdots +y}^{24} +z}_{26} \]
Apparently the "24" should be directly above the overbrace and the "26"
directly underneath the underbrace.
Doing pretty well though...
I've gone through the whole of the math section from Lmport's book and tried
all the different symbols etc. The only stuff that I've found I can't type in
pseudo-LaTeX fashion and get it displayed is
\mathrm abc or \mathcal A, etc
\sqrt[n] 2
\emptyset is displayed, but incorrectly.
in addition "\{" creates both brackets whereas the other delimiter ops
produce only one.
Going through the tables in detail (I inserted some spaces for readability),
the following do not display. You might keep this for reference or something.
