Eskimo bowline sheet bend. (The image above with red rope would result in an ends-opposite (and inferior) sheet bend; the version shown on the right side would give a same-side sheet bend (ABoK #1431). The common bowline when ring-loaded becomes effectively an inferior version of the Lapp bend, and so can slip and untie; the wrongly demeaned "left-handed"/"cowboy" bowline becomes the proper Lapp bend, and should hold.) A Cossack knot is another name for the same knot. A slipped version of the Cossack knot is called Kalmyk loop. Eskimo bowline The Eskimo bowline is an 'anti-bowline' which is in a class of
Arf invariant of a knot slice knot is a square integer. As formula_12 is an odd integer, it has to be congruent to 1 modulo 8. Combined with Murasugi's result this shows that the Arf invariant of a slice knot vanishes. Arf invariant of a knot In the mathematical field of knot theory, the Arf invariant of a knot, named after Cahit Arf, is a knot invariant obtained from a quadratic form associated to a Seifert surface. If "F" is a Seifert surface of a knot, then the homology group H("F", Z/2Z) has a quadratic form whose value is the number of full twists mod
