tautological set

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.
