==Definition==&lt;br /&gt;
&lt;br /&gt;
A [[natural number]] &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; is termed a &amp;#039;&amp;#039;&amp;#039;highly composite number&amp;#039;&amp;#039;&amp;#039; if it is a [[defining ingredient::strict maximum-so-far]] for the [[defining ingredient::divisor count function]]. In other words, if &amp;lt;math&amp;gt;\tau(n)&amp;lt;/math&amp;gt; denotes the number of divisors of &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt;, then &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; is highly composite if &amp;lt;math&amp;gt;\tau(n) &amp;gt; \tau(k)&amp;lt;/math&amp;gt; for every natural number &amp;lt;math&amp;gt;k &amp;lt; n&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
==Relation with other properties==&lt;br /&gt;
&lt;br /&gt;
* [[Superabundant number]] is a closely related notion -- it is a [[strict maximum-so-far]] for the ratio of the [[divisor sum function]] to the number itself.&lt;/div&gt;</summary>
