WebCell Constraints. The key to proving the Cook-Levin Theorem is to break up the different types of conditions we need to enforce into individual formulas that we will end up combining at the end of the proof. As a first step, we need to ensure that the Boolean variables x_ {i,j,\sigma} xi,j,σ really encode a tableau (valid or not).
