In the course of working on some propositional logic/SAT applications, I came across an interesting identity I don’t think I knew of before. It seems related to all kinds of stuff, but I guess that’s not unusual for math… Anyhow, this particular identity made it very easy to transform some assertions I needed from disjunctive normal form to conjunctive normal form. It’s also beautiful on its own, so I thought I’d write it down.
