Hey, sorry to interrupt, but as a non-professional mathematician, I can confidently tell you that you're overcomplicating things.

What you're actually looking at is just a trivial crystallographic Simple Cubic system of Argon, Boron, Carbon, Potassium, Lithium, Magnesium, Phosphorus, Quarks (obviously!), and Radon under elastic constraint. Naturally!

Unless it's a plastic deformation...

Or? wait, what's that? there two types of forces?

Let me kindly ask my colleague Dunning-Krugger: He knows everything on the subject.
