logic A notion introduced by Florentin Smarandache: An
element x(T, I, F) belongs more than sure to the
set M; here
T, I, F are real subsets representing the truth,
indeterminacy, and falsity percentages respectively, and
sup(T)@#100.
tautological set are used for universally true propositions
where no parameter such as time, space, or subjectivity
influences the truth value.
