Can you be a little more specific about what you need more details on?  I&#x27;d be happy to write a little more, put some extra links or text boxes to clarify, but I&#x27;m not sure what people need explaining.<p>Does this help?<p><a href="http:&#x2F;&#x2F;www.solipsys.co.uk&#x2F;new&#x2F;GraphThreeColouring.html?HN2" rel="nofollow">http:&#x2F;&#x2F;www.solipsys.co.uk&#x2F;new&#x2F;GraphThreeColouring.html?HN2</a><p>Feel free to email if you&#x27;d prefer, I&#x27;ll go and start reviewing it.<p>Thanks!<p><i>Edit: I&#x27;ve now added a side-box with that link.</i>
