<h3 class="section">9.1 The Permutation struct</h3>
<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,
<pre class="example"> typedef struct
{
size_t size;
size_t * data;
} gsl_permutation;
</pre>
