program in question; operations on the lattice help us combine these facts

Interestingly, lattices can be made by combining other lattices in certain

ways. We can therefore use simpler lattices as building blocks to create

more complex ones, all while preserving the algebraic structure that

I've decided that the purpose of a blog is to actually use it every once in a while. So, to fill up this blank space, I'll be documenting my own experience of starting to learn how emulation works. I'd like to say right now that my main goal was not to learn emulation. Rather, I needed to emulate to refresh my skills for a different subject area. However, emulation turned out fun enough to write about.
