In knot theory, the 6 2 knot is one of three prime knots with crossing number six, the others being the stevedore knot and the 6 3 knot.This knot is sometimes referred to as the Miller Institute knot, [1] because it appears in the logo [2] of the Miller Institute for Basic Research in Science at the University of California, Berkeley.
A2 Key (previously known as the Key English Test (KET) and Cambridge English: Key) was developed through trials conducted between 1991 and 1994. [ 2 ] It was created to offer students a basic qualification in English and provide the first step for those wishing to progress towards higher level qualifications, such as B1 Preliminary , B2 First ...
An example is 1*2 −3 2. The 1* denotes the only 1-vertex basic polyhedron. The 2 −3 2 is a sequence describing the continued fraction associated to a rational tangle. One inserts this tangle at the vertex of the basic polyhedron 1*. A more complicated example is 8*3.1.2 0.1.1.1.1.1 Here again 8* refers to a basic polyhedron with 8 vertices.
Like the figure-eight knot, the 6 3 knot is fully amphichiral.This means that the 6 3 knot is amphichiral, [2] meaning that it is indistinguishable from its own mirror image. In addition, it is also invertible, meaning that orienting the curve in either direction yields the same oriented knot.
