An intertwining of a circle with a clover leaf loop .
In knot theory , a branch of mathematics , an entanglement (also a link or concatenation ) is a set of knots that do not intersect, but that can be intertwined.
The projection of a link onto a plane is known as a link diagram .
The mathematician Carl Friedrich Gauß found the link number to be one of the first invariants for links.
