st: recognizing patterns within two columns of data

Hello,
I would like some advice on how to do the following. Here is how the data looks:
compA holderA
compB holderA
compC holderL
compD holderH
compA holderB
compB holderB
compC holderB
Above, there was more than one instance where compA and compB had the same holder. In a large database, how do I identify instances where a set of comps appear repeatedly with the same holders?
Thanks. I appreciate any advice.
best
Dalhia Mani
