==Statement==&lt;br /&gt;
&lt;br /&gt;
The conjecture is that there exist infinitely many [[regular prime]]s. A regular prime is a prime for which the corresponding [[cyclotomic ring]] is a [[unique factorization domain]], or equivalently, a ring whose class number is one.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
* [[Distribution conjecture for regular primes]]: This conjecture states that the limit, as &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; tends to &amp;lt;math&amp;gt;\infty&amp;lt;/math&amp;gt;, of the fraction of primes less than &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; that are regular, is &amp;lt;math&amp;gt;e^{-1/2} \simeq 0.6065&amp;lt;/math&amp;gt;.&lt;/div&gt;</summary>
