get1

get_cyc

permutation object (coerced to <code>cycle</code> class)

In function <code>get1()</code>, argument <code>drop</code> controls
 the behaviour if <code>x</code> is length 1. If <code>drop</code> is
 <code>TRUE</code>, then a vector of representative elements is returned;
 if <code>FALSE</code>, then a list with one vector element is returned

drop

Length-one vector interpreted as a permutation object

Given an object of class <code>cycle</code>, function <code>get1()</code> returns a
representative of each of the disjoint cycles in the object's elements.
Function <code>get_cyc()</code> returns the cycle containing a specific element.

Manipulates invertible functions from a finite set to itself.  Can transform from word form to cycle form and back.
