Unknotting number. Trefoil knot without 3-fold symmetry being unknotted by one crossing switch. In the mathematical area of knot theory, the unknotting number of a knot is the minimum number of times the knot must be passed through itself ( crossing switch) to untie it. If a knot has unknotting number , then there exists a diagram of the knot ...
411 (telephone number) 411 is a telephone number for local directory assistance in Canada and the United States. Until the early 1980s, 411 – and the related 113 number – were free to call in most jurisdictions.

Telephone directory. A telephone directory, commonly called a telephone book, telephone address book, phonebook, or the white and yellow pages, is a listing of telephone subscribers in a geographical area or subscribers to services provided by the organization that publishes the directory. Its purpose is to allow the telephone number of a ...
Every non-trivial knot has bridge number at least two, so the knots that minimize the bridge number (other than the unknot) are the 2-bridge knots. It can be shown that every n-bridge knot can be decomposed into two trivial n-tangles and hence 2-bridge knots are rational knots. If K is the connected sum of K 1 and K 2, then the bridge number of ...

Unknot. In the mathematical theory of knots, the unknot, not knot, or trivial knot, is the least knotted of all knots. Intuitively, the unknot is a closed loop of rope without a knot tied into it, unknotted. To a knot theorist, an unknot is any embedded topological circle in the 3-sphere that is ambient isotopic (that is, deformable) to a ...
