[Cialug] Need An Algo Suggestion

[Todd Walton]

I'm not a programmer. Not really. If I had a list of things like this:

 1,2
 2,3
 2,4
 3,6

how would I map them so that I can see that 1 refers to 2, 2 refers to 3
and 4, and 3 refers to 6, so:

 1,2,3,6
 1,2,4
 2,3,6
 2,4
 3,6

Like that? I want to build up those chains. Every chain has an end. There's
no infinite loops. But some have multiple paths.

I'm not sure how to do that, and I'm not sure what to call it for the
purposes of DDGing it.
