==Definition==&lt;br /&gt;
&lt;br /&gt;
A subgroup property &amp;lt;math&amp;gt;p&amp;lt;/math&amp;gt; is termed &amp;#039;&amp;#039;&amp;#039;strongly UL-intersection-closed&amp;#039;&amp;#039;&amp;#039; if for any group &amp;lt;math&amp;gt;G&amp;lt;/math&amp;gt;, any (possibly empty) indexing set &amp;lt;math&amp;gt;I&amp;lt;/math&amp;gt;, and subgroups &amp;lt;matH&amp;gt;H_i \le K_i \le G, i \in I&amp;lt;/math&amp;gt;, such that &amp;lt;math&amp;gt;H_i&amp;lt;/math&amp;gt; satisfies property &amp;lt;math&amp;gt;p&amp;lt;/math&amp;gt; in &amp;lt;math&amp;gt;K_i&amp;lt;/math&amp;gt; for each &amp;lt;math&amp;gt;i \in I&amp;lt;/math&amp;gt;, we have:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;\bigcap_{i \in I} H_i&amp;lt;/math&amp;gt; satisfies property &amp;lt;math&amp;gt;p&amp;lt;/math&amp;gt; in &amp;lt;math&amp;gt;\bigcap_{i \in I} K_i&amp;lt;/math&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
A subgroup property is strongly UL-intersection-closed if and only if it is both [[UL-intersection-closed subgroup property|UL-intersection-closed]] and [[identity-true subgroup property|identity-true]].&lt;br /&gt;
&lt;br /&gt;
