At least one probem in your code is that you are calling
(geometric-objects-duplicates ....
(list ((geometric-objects-duplicates ....) (geometric-objects-
duplicates ....))
What you are passing to the outer geometric-objects-duplicates call is
not a list of objects (as required), but a list of two lists of
objects. A list of lists is not the same thing as a single list; to
combine the lists from the two inner geometric-objects-duplicates
calls, you need to use "append", not "list".
