<p>A permutation is defined by a structure containing two components, the size
of the permutation and a pointer to the permutation array.  The elements
of the permutation array are all of type <code>size_t</code>.  The
<code>gsl_permutation</code> structure looks like this,

<div class="example">
<pre class="example">typedef struct
{
  size_t size;
  size_t * data;
} gsl_permutation;
