&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;Computing the tricolouring invariant efficiently&amp;#039;&amp;#039;: A priori, it is an exponential time problem since for a knot diagram with &amp;lt;math&amp;gt;n&amp;lt;/math&amp;gt; arcs we need to consider &amp;lt;math&amp;gt;3^n&amp;lt;/math&amp;gt; possible colourings. However, the problem can be reduced to Gaussian elimination over &amp;lt;math&amp;gt;Z/3Z&amp;lt;/math&amp;gt; and quadratic time. For more details see [[AKT-09/Tricolourability]].&lt;/div&gt;</summary>
