That's easy. Just define 'product' as a function that finds the cartesian product of any number of lists, and then once you've done that you can apply it to make the special case of three items like this:

cartesianProduct a b c = product [a,b,c]

At least, that's how I would do it.

eesh, 'product' is something else in the Prelude. Better call it 'cartprod' or something. -- Ashley Yakeley, Seattle WA
