7 1 knot, septafoil knot, (7,2)-torus knot - a prime knot with crossing number seven, which can be arranged as a {7/2} star polygon ; 7 4 knot, "endless knot" 8 18 knot, "carrick mat" 10 161 /10 162, known as the Perko pair; this was a single knot listed twice in Dale Rolfsen's knot table; the duplication was discovered by Kenneth Perko
Thief knot – resembles the reef knot except that the free, or working, ends are on opposite sides; Threefoil knot – another term for a trefoil knot; Thumb knot a.k.a. overhand knot – one of the most fundamental knots and forms the basis of many others; Timber hitch – used to attach a single length of rope to a cylindrical object
The main problem studied in the book is the use of knot invariants to test whether a loop is knotted or distinguish knots from each other. [1] [2] It has seven short chapters, [3] separated by "interludes" providing examples including Celtic knots, knotted papercraft, neckties, ropework, torus knots, and a form of the trefoil knot that can only sit on a plane with two points in contact.

The reef knot can capsize if one of its standing ends is pulled.. A knot that has capsized or spilled has deformed into a different structure. Although capsizing is sometimes the result of incorrect tying or misuse, it can also be done purposefully in certain cases to strengthen the knot (see the carrick bend [4]) or to untie a seized knot which would otherwise be difficult to release (see ...
The Ashley Book of Knots was compiled and first published before the introduction of synthetic fiber ropes, during a time when natural fiber cordage – typically twisted, laid, or braided rope – was most commonly used. The commentary on some knots may fail to address their behavior when tied with modern synthetic fiber or kernmantle style ropes.
The early tables attempted to list all knots of at most 10 crossings, and all alternating knots of 11 crossings (Hoste, Thistlethwaite & Weeks 1998). The development of knot theory due to Alexander, Reidemeister, Seifert, and others eased the task of verification and tables of knots up to and including 9 crossings were published by Alexander ...
