<h4>1.1 <span class="Heading">
Introduction
</span></h4>
<p>This is the manual for the <strong class="pkg">Semigroups</strong> package for <strong class="pkg">GAP</strong> version 5.5.4. <strong class="pkg">Semigroups</strong> 5.5.4 is a distant descendant of the <span class="URL"><a href=" http://schmidt.nuigalway.ie/monoid/index.html">Monoid package for GAP 3</a></span> by Goetz Pfeiffer, Steve A. Linton, Edmund F. Robertson, and Nik Ruskuc.</p>
<p>From Version 3.0.0, <strong class="pkg">Semigroups</strong> includes a copy of the <span class="URL"><a href="https://libsemigroups.readthedocs.io/en/latest/">libsemigroups</a></span> C++ library which contains implementations of the Froidure-Pin, Todd-Coxeter, and Knuth-Bendix algorithms (among others) that <strong class="pkg">Semigroups</strong> utilises.</p>
<p>If you find a bug or an issue with the package, please visit the <span class="URL"><a href=" https://github.com/semigroups/Semigroups/issues ">issue tracker</a></span>.</p>
