WebMy answer above assumes a right-to-left composition, so that. ( 1 3) ( 2 3 5) = ( 1 3 5 2), for example. If instead, you're using left-to-right composition, so that. ( 1 3) ( 2 3 5) = ( 1 5 2 3), then we'll take a similar approach to the above, but addressing the cycles in the opposite order. In particular, for example, ( 1 5 3 2) sends 1 to 5 ... A permutation is called a cyclic permutation if and only if it has a single nontrivial cycle (a cycle of length > 1). For example, the permutation, written in two-line notation (in two ways) and also cycle notation, $${\displaystyle {\begin{pmatrix}1&2&3&4&5&6&7&8\\4&… In mathematics, and in particular in group theory, a cyclic permutation (or cycle) is a permutation of the elements of some set X which maps the elements of some subset S of X to each other in a cyclic fashion, while fixing (that is, … See more • Cycle sort – a sorting algorithm that is based on the idea that the permutation to be sorted can be factored into cycles, which can … See more This article incorporates material from cycle on PlanetMath, which is licensed under the Creative Commons Attribution/Share-Alike License.

WebPermutation notation is fine for computations, but is cumbersome for writing permutations. We can represent permutations more concisely using cycle notation. The idea is like factoring an integer into a product of primes; in this case, the elementary pieces are called cycles. Definition.

WebIf $(123)$ is in "cycle notation", then this means that $1$ maps to $2$, $2$ maps to $3$, and $3$ (the last term in the cycle) maps to $1$. That is, ... A more general permutation could look like $(1 4 5)(2 6)$ which means 1 goes to 4 who goes to 5 who goes back to 1, while 2 and 6 swap places and (implied) 3 stays put. Share.
