== Abelian groups vs modules ==
Normally you'd call these abelian groups, or possibly Z-modules, because just calling them modules suggests things which aren't true. I suggest changing this to "abelian groups", which is what it would normally be called and what I've been calling it.

OK, but what's the "dual group" of an abelian group? Is it well-defined?

And what's the terminology I should use for the fundamental "spaces" in matrices then?

I see there's some precedence for talking about the "column module", "row module", "null module" of an integer matrix acting as a linear transformation on a Z-module, instead of column space, row space, etc. Would I call it the "column group" and "row group"? Would anyone know what I mean?

Note also I explicitly spelled it out here at the top

But I'm curious what things I wrote aren't true of modules in general and only of Z-modules.
