Summary :

A quaternary Boolean ring structure is introduced to the four-element set L={0,,,1}, which is the only Boolean ring structure possible on it; the set of logic functions on L and L2 expressible over the ring is extended from the Boolean polynomials to the entire logic functions; the extension becomes possible after inclusion of two non-Boolean polynomials in the basis, where the number is the smallest possible one. A one-to-one mapping between L and {0,1,2,3} is made, and resulting arithmetic operations on L are make explicit in the form of monadic or dyadic functions.
