Comparing lists in Lisp
I could figure out some way to do this myself but I have a feeling there's a simpler, perhaps built-in way to do this. I want to see if any two lists share an element. These are the two lists I'm dealing with at the moment:

    ((0 1 2) (3 4 5) (6 7 8) (0 3 6) (1 3 7) (2 4 8) (0 4 8) (2 4 6))

    ((0 1 7) (0 1 6) (0 1 3) (0 3 7) (0 3 6) (0 6 7) (1 3 7) (1 3 6) (1 6 7) (3 6 7)) 

Since both lists contain `(1 3 7)`, I'd like a comparison of the lists to return `T`.

Is there a better way to do this than just setting up a couple `DOLIST`s?
