'(a b c) is | '((a b c) (a b) (a c) (b c) (a) (b) (c) nil) | It should work for any number of elements in a set. what is the difference between (power '(b c)) and (power '(a b c))? this should allow you to make a recursive definition, and ... voila! #<Erik> -- miracle of miracles. look what the Net dragged in.
