Image Oriental tie knot.jpg thumb A small knot The small knot , or oriental knot or Kent knot , is the simplest method of tying a necktie , though some claim the simple knot is an alternate name for the four in hand knot . The small knot is not very well known despite its simplicity.

multiple issues unref April 2011 wikify April 2011 As a type of List of binding knots binding knot , the Jamming Knot is good for constricting a bundle of objects such as sticks or brush. It is basically a taut line hitch but the initial two wraps are on the outside of the working line rather than on the inside, and finished off with one wrap on the inside. Thus the knot holds tension towards the inside of the loop rather than the standing end of the rope as with the taut line turning a tension knot into a constricting knot. After the knot is tied, the knot is held with one hand, the standing end is pulled tight, and the knot should hold fast. This knot, as with the taut line, can be difficult or impossible to tie on slick or particularly stiff rope. References The author of this article found this knot on E How.

In mathematics , a knot mathematics knot is an embedding of a circle into 3 dimensional Euclidean space . The knot group of a knot K is defined as the fundamental group of the knot complement of K in R sup 3 sup , math pi 1 mathbb R 3 backslash K . math Other conventions consider knots to be embedded in the 3 sphere, in which case the knot group is the fundamental group of its complement in S sup 3 sup Properties Two equivalent knots have isomorphic knot groups, so the knot group is a knot invariant and can be used to distinguish between inequivalent knots. This is because an equivalence between two knots is a self homeomorphism of math mathbb R 3 math isotopic to the identity sending the first knot onto the second. Clearly the homeomorphism restricts onto a homeomorphism of the complement of the knot therefore inducing an isomorphism in the fundamental group of the knot complement. However, two knots can have isomorphic knot groups without necessarily being equivalent see below for an example . The abelianization of a knot group is always isomorphic to the infinite cyclic group Z this follows because the abelianization agrees with the first homology group , which can be easily computed. The knot group or fundamental group of an oriented link in general can be computed in the Wirtinger presentation by a relatively simple algorithm. Examples The unknot has knot group isomorphic to Z .

In mathematics , the knot complement of a tame knot K is the three dimensional space surrounding the knot. To make this precise, suppose that K is a knot in a three manifold M most often, M is the 3 sphere . Let N be a thickened neighborhood of K so N is a solid torus . The knot complement is then the complement set theory complement of N , math X K M mbox interior N . math The knot complement X sub K sub is a compact space compact 3 manifold the boundary of X sub K sub and the boundary of the neighborhood N are homeomorphic to a two torus . Sometimes the ambient manifold M is understood to be 3 sphere . Context is needed to determine the usage. There are analogous definitions of link knot theory link complement . Many knot invariant s, such as the knot group , are really invariants of the complement of the knot. When the ambient space is the three sphere no information is lost the Gordon&ndash Luecke theorem states that a knot is determined by its complement. That is, if K and K &prime are two knots with homeomorphic complements then there is a homeomorphism of the three sphere taking one knot to the other. References C. Gordon and J.

Its round shape, especially when tied in stiff rope, helps it slide freely along the rope it is tied around. To tie, first place an overhand knot in the end of the rope. Then tie a second overhand knot, pass the running end of the rope through it, and tighten. A Lariat Loop is similarly constructed but will not slip from the running end. To tie a Lariat Loop first tie an overhand knot, then pinch it so that the running end slides freely back and forth. Pass the rope end through just that free sliding loop, and tighten. The photograph at right displays a Lariat Loop, with an additional overhand knot acting as a stopper knot because the lariat loop can slip by way of the rope s end when tension is not applied to the running end.
