Links
- Borromean rings - three topological circles which are linked and form a Brunnian link
- Brunnian link - a nontrivial link that becomes trivial if any component is removed
- Hopf link - the simplest nontrivial link with more than one component; it consists of two circles linked together exactly once
- Pretzel link - a Montesinos link with integer tangles
- Solomon's knot (a "link" rather than a "knot" according to the conventions of the mathematical theory of knots) - a traditional decorative motif used since ancient times
- Unlink - equivalent under ambient isotopy to finitely many disjoint circles in the plane
- Whitehead link - two projections of the unknot: one circular loop and one figure eight-shaped loop intertwined such that they are inseparable and neither loses its form

Famous quotes containing the word links:
“An alliance is like a chain. It is not made stronger by adding weak links to it. A great power like the United States gains no advantage and it loses prestige by offering, indeed peddling, its alliances to all and sundry. An alliance should be hard diplomatic currency, valuable and hard to get, and not inflationary paper from the mimeograph machine in the State Department.”
—Walter Lippmann (1889–1974)
“Ibsen is like this room where we are sitting, with all the tables and chairs. Do I care whether you have twenty or twenty-five links on your chain? Hedda Gabler, Nora and the rest: it is not that I want! I want Rome and the Coliseum, the Acropolis, Athens; I want beauty, and the flame of life.”
—Eleonora Duse (1859–1924)
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
