The standard braid is Brunnian: if one removes the black strand, the blue strand is always on top of the red strand, and they are thus not braided around each other; likewise for removing other strands. A Brunnian braid is a braid that becomes trivial upon removal of any one of its strings. Brunnian braids form a subgroup of the braid group.
One example of a modern witch's ladder is a string of 40 beads or a cord with 40 knots. Sometimes feathers, bones, and other trinkets are braided into the string as symbols for a desired spell effect. An earlier version of a witch's ladder consisted of a rope or cord of three, nine, or thirteen knots.
In knot theory, the trefoil is the first nontrivial knot, and is the only knot with crossing number three. It is a prime knot, and is listed as 3 1 in the Alexander-Briggs notation. The Dowker notation for the trefoil is 4 6 2, and the Conway notation is [3]. The trefoil can be described as the (2,3)-torus knot.

Siberian hitch – used to attach a rope to an object; Simple knot – (four-in-hand knot) a method of tying a necktie; Simple Simon over – used for joining two lines; Simple Simon under – used for joining two lines. It is more secure than the similar Simple Simon over. Single carrick bend – refers to different knots similar to the ...
Create a loop in the rope. Then pull a bight of the working part through the loop, creating an overhand noose knot. Pull another bight of the working part through the loop of the previous stitch. Tighten the stitch to the desired degree by pulling on both sides of the loop. Adjust the loop by pulling on the working end to keep it a reasonable size.
Tubular fids aid in splicing double-braided rope. Top fids are used to pull rope taut while separating strands of rope with a Swedish fid. Uni-fids are needed to splice braid with a parallel core. A marlinspike is a tool, usually made of steel and often part of a sailor's pocketknife, which is used to separate strands of rope from one another ...
