Analogous laws

Statement

Some systems of logic have different but analogous laws. For some finite n-valued logics, there is an analogous law called the law of excludedn*+1th*. If negation is cyclic and "∨" is a "max operator", then the law can be expressed in the object language by (P ∨ ~P ∨ ~~P ∨ ... ∨ ...P), where "..." represents n−1 negation signs and "∨ ... ∨" n−1 disjunction signs. It is easy to check that the sentence must receive at least one of the n truth values (and not a value that is not one of the n).

Other systems reject the law entirely.
