Set

If   1 2 { , ,..., }, n   

for n  2 , then

1 2 { , ,..., , } n D I    

where I = indeterminacy means neither 1 , nor 2 , ..., nor n  , or neither any parts (intersections) of some of them, or all of them in the same time, or only a part of them in the same time, or empty set, or unknown. If so, there are in neutrosophic logic connectors which connect such masses.

Three-Way Decision Space as particular case of Neutrosophic Set

P. K. Singh Three-way decision space provides us a way to classify the given information into the acceptation, rejection, and uncertain regions. Florentin Smarandache "acceptation, rejection and uncertain" is exactly the neutrosophy, or the neutrosophic set.

Finite Three-Valued Logic & Triple-Infinite Three Valued-Logic

Ion Pătrașcu Lukasiewicz did a finite three-valued logic, while

Smarandache did an infinite three-valued logic (you have a degree of truth, degree of falsehood, and degree of
