      <itunes:summary>&lt;p&gt;I find it very useful, thanks. Can you kindly enumerate&amp;nbsp; all monoids of order 6 as another example?&lt;/p&gt;</itunes:summary>

      <title>There are 2237 monoids of order 6</title>

      <itunes:summary>&lt;p&gt;Sure. The 'monoid' property is one of the builtin properties, so you can just pass that name as a keyword option. The command&lt;/p&gt;
&lt;pre&gt;&amp;gt; Magma:-Enumerate( 6, 'monoid' );
                             2237
&lt;/pre&gt;
&lt;p&gt;does the job. Using this, it is easy to construct a table of the numbers of isomorphism classes of monoids up to order 7.&lt;/p&gt;
&lt;pre&gt;  Order        No. Monoids
    2                 2
    3                 7
    4                35
    5               228
    6              2237
    7             31559
    8           1668997
&lt;/pre&gt;
&lt;p&gt;The order 8 result takes quite awhile to run, and saving the results produced a file of about 350 Mb!&lt;/p&gt;</itunes:summary>
