I recently asked a question on TeX SE about how to draw lattice diagrams with MathJax (as in, the TeX commands for creating one, once I already drew it on paper and know what it should look like). Unfortunately I learned that MathJax isn't really what they cover over there. Then, I searched through the documentation but I couldn't find anything either.
So I ask here instead, and my question is: How do I code a lattice such as the following (this one is just an image) so it'll work on Math SE?:
I'll also accept a redirect to a helpful page. Here is a link to the original question: https://tex.stackexchange.com/questions/219005/help-on-simple-lattice-diagrams?noredirect=1#219029
Edit: The term I should be using is Hasse Diagram.
