In mathematics, the braid group on n strands (denoted $${\displaystyle B_{n}}$$), also known as the Artin braid group, is the group whose elements are equivalence classes of n-braids (e.g. under ambient isotopy), and whose group operation is composition of braids (see § Introduction). Example applications of braid … See more In this introduction let n = 4; the generalization to other values of n will be straightforward.
