Made a start on modular lattice.
I have added a disambiguation line at the top, and created a stub for modular integral lattice. I also created a page lattice (disambiguation).
I don’t see the disambiguation line; did you notice I was editing for the last hour or so?
Oh, I see, you added the line to lattice, not modular lattice.
I have now added a disambiguation line also to modular lattice. (I thought I did this before, but also certainly I did wait for you to unlock the entry. So apparently in the end I forgot to do it after all.)
Thanks! It’s amusing to me that we have two pairs of terms to disambiguate in this way (probably equally well entrenched in their respective communities).
Yes. Of course most famous is the notion of unimodular lattice.
Ever since we have the entry lattice I keep having the thought that “most” people will not expect the order theoretic notion by default. But then, “most” strongly depends on context, of course.

That’s funny, because in my day-to-day life I think about the order-theoretic notion much more often than about discrete free abelian subgroups of maximal rank. Anyway, I’m glad you constructed the disambiguation page.
Flashback: When I was a graduate student at Rutgers, I.M. Gel’fand would, for unfathomable reasons, frequently ask speakers in his seminar if they knew about the free modular lattice on 3 generators, and particularly if they knew how many elements it contained. (Answer: 28.) It seems he was much taken with modular lattices and their linear representations.
I added a snippet to the section on free modular lattices, mentioning briefly the current Café discussion.
