  2. The Knot Atlas - Wikipedia

    en.wikipedia.org/wiki/The_Knot_Atlas

    The Knot Atlas is a website, an encyclopedia rather than atlas, dedicated to knot theory. It and its predecessor were created by mathematician Dror Bar-Natan, who maintains the current site with Scott Morrison. According to Schiller, the site contains, "beautiful illustrations and detailed information about knots," as does KnotPlot.com. [1]

  3. Arris - Wikipedia

    The origin of the term arris is from the Latin arista, meaning the beard or the ear of grain or the bone of a fish. See also arête. An arris rail is a structural element, whose cross section is a 45 degree isosceles right angled triangle. Arris rails are usually made of wood, and are manufactured by cutting a length of square-section timber ...

  6. List of prime knots - Wikipedia

    en.wikipedia.org/wiki/List_of_prime_knots

    In knot theory, prime knots are those knots that are indecomposable under the operation of knot sum. The prime knots with ten or fewer crossings are listed here for quick comparison of their properties and varied naming schemes.

  7. Reever Knot - Wikipedia

    en.wikipedia.org/wiki/Reever_Knot

    The relationship between the Reever Knot and the Vice Versa Bend was first pointed out by Clements In his 2004 article "The Vice Versa Bend and the Reever Knot". [1] His analysis of the symmetry of the two forms of the knot led him to suggest that the Reever Knot, being completely symmetric, is the better version of the knot.

  9. Knot operation - Wikipedia

    en.wikipedia.org/wiki/Knot_operation

    In knot theory, a knot move or operation is a change or changes which preserve crossing number. [1] Operations are used to investigate whether knots are equivalent, prime or reduced . Knot moves or operations include the flype , Habiro move , Markov moves (I. conjugation and II. stabilization), pass move , Perko move , and Reidemeister moves (I ...
