Therefore, implication and F can be combined to an inverter. P implies Q can be written as Q or not P. Both have the same truth tables. This demonstrates, that implication is equivalent to a disjunction with ... WebOne commonly used (redundant) expressively complete set is {NOT, AND, OR}. Two particularly common canonical sets of expressions over this set are the conjunctive normal form (CNF) and disjunctive normal form (DNF). Both of these are rather verbose. There is also a notion of a minimal expression over a set of connectives, defined variously.
