Get 3 most common Point from List<Point>
<p>I have a quick question that I haven't found out how to do efficiently (in C#).</p>

<p>I have a list array of Points (X,Y). I need to find which 3 points are the tightest cluster. It's for a mapping project.</p>

<p>What would the best way to do this be? There's only about 6 to 9 items in the list.</p>

<p>Thanks in advance.</p>

<p>Cheers!</p>
