The figure-eight or figure-of-eight knot is also called (in books) the Flemish knot. The name figure-of-eight knot appears in Lever's Sheet Anchor; or, a Key to Rigging (London, 1808). The word "of" is nowadays usually omitted. The knot is the sailor's common single-strand stopper knot and is tied in the ends of tackle falls and running rigging ...
This list of knots includes many alternative names for common knots and lashings. Knot names have evolved over time, and there are many conflicting or confusing naming issues. The overhand knot, for example, is also known as the thumb knot. The figure-eight knot is also known as the Savoy knot or the Flemish knot.
A: open loop, B: closed loop, C: turn, D: round turn, and E: two round turns. In reference to knots, loop may refer to: One of the fundamental structures used to tie knots. Specifically, it is a U-form narrower than a bight. [17] A type of knot used to create a closed circle in a line. A loop is one of the fundamental structures used to tie knots.
Figure-eight knot of practical knot-tying, with ends joined. In knot theory, a figure-eight knot (also called Listing's knot[1]) is the unique knot with a crossing number of four. This makes it the knot with the third-smallest possible crossing number, after the unknot and the trefoil knot. The figure-eight knot is a prime knot.
The simplest knot, called the unknot or trivial knot, is a round circle embedded in R 3. [4] In the ordinary sense of the word, the unknot is not "knotted" at all. The simplest nontrivial knots are the trefoil knot (3 1 in the table), the figure-eight knot (4 1) and the cinquefoil knot (5 1). [5] Several knots, linked or tangled together, are ...
A cut splice is a join between two ropes, made by side splicing the ends slightly apart, to make an eye in the joined rope which lies shut when the rope is taut. Its original name was bowdlerised to "cut splice". A line eye-spliced to a snap shackle. Eye splice – A splice where the working end is spliced into the working part forming a loop.
The figure-eight knot is the simplest amphicheiral knot. An amphicheiral knot is one which has an orientation-reversing self-homeomorphism of the 3-sphere, α, fixing the knot set-wise. All amphicheiral alternating knots have even crossing number. The first amphicheiral knot with odd crossing number is a 15-crossing knot discovered by Hoste et ...
In geometry, a figure is chiral (and said to have chirality) if it is not identical to its mirror image, or, more precisely, if it cannot be mapped to its mirror image by rotations and translations alone. An object that is not chiral is said to be achiral. A chiral object and its mirror image are said to be enantiomorphs.
