Combinations of Points

I have a set of 8 unique points, and I need to cycle through all possible routes between those points, [preferably] using recursion.

How do I go about a problem like this?

I'm not particularly well versed in recursion, so it's all a bit strange to me... where do I start?
Start with Google you stupid piece of shit, /prog/ isn't for CS101 questions.
