hi, I have a data problem that I was hoping someone could help me fix using stata.  I have data on joint venture deals between participant companies.  

Here is how my data looks like:
Deal_Number1, Participant_1
Deal_Number1, Participant_2
Deal_Number1, Participant_3
Deal_Number2, Participant_1
Deal_Number2, Participant_2

Here is what I need it to look like:
Deal_Number1, Participant_1, Participant_2
Deal_Number1, Participant_1, Participant_3
Deal_Number1, Participant_2, Participant_3
Deal_Number2, Participant_1, Participant_2

So basically, I need a permutation combination of all pairs of participants in a deal.  I will be extremely grateful if anyone out there can suggest a way of doing this.
