13. A echange is often displayed by the periods it has. For example , if we permute the figures in the all-natural order to a couple of 3 1 5 5, this is represented as (1 3 2) (5 4). In this the (132) says that the initially number has gone to the location 3, the next number has gone to the location 2, and the second number has gone to put 1, and (5 4) means that the fifth amount has gone to put 4 and the fourth number has gone to put 5. The numbers with brackets need to be read cyclically.

If a amount has not changed placement, it is stored as a sole cycle. As a result 5 a couple of 1 several 4 can be represented because (1345)(2).

We might apply mixtures on by itself If we apply the echange (132)(54) when, we get 2 3 1 5 some.
