If n is a list or set, then randperm returns a random permutation of the elements of n. If n is a positive integer, then a random permutation of the first n positive integers is returned.

The command with(combinat,randperm) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{combinat}\,\mathrm{randperm}\right)$

$\left[\mathrm{randperm}\right]$

$\mathrm{randperm}\left(3\right)$

$\left[3\,2\,1\right]$

$\mathrm{randperm}\left(\left[a\,b\,c\,d\right]\right)$

$\left[b\,c\,d\,a\right]$

$\mathrm{randperm}\left(\left\{W\,X\,Y\,Z\right\}\right)$

$\left[X\,W\,Z\,Y\right]$
