Ouch!

When you look at the entire TOC, yes.  But what if you land in that
section in Info, by following some cross-reference or index search?

If others don't mind (and if the consideration I mention above doesn't
make you change your mind), then I won't object.  Just make sure we
don't already have other sections by the same name.

Because it's an @unnumberedsec for some reason.  Change it to
@section, and you will have the number.  The same goes for "Notation
and Terminology".

Thanks for spotting these blunders.
