advice on permutations/combinations sofware for input data

Oct 18, 2011 at 3:45 PM

I would like to know if any of you is using a software to generate permutations that can be then used to create the edges. My input data is a list of organisations working together, each organisation in a different cell of an Excel tab and I would like to have all the unique pairs so as to create my edges easily. Any idea or reference?

thanks in advance

Given three organizations, do you want this:

Org1, Org2
Org1, Org3
Org2, Org3

...or do you want this:

Org1, Org2
Org1, Org3
Org2, Org1
Org2, Org3
Org3, Org1
Org3, Org2

In the first case order doesn't matter; in the second case it does.

First case is the one I am interested in
