        Maybe I am lost, and I guess I truly am since I deleted the first
email on this subject, but didn't the original problem state that the three
circles all have a radius equal to 1 unit?  If so, how can you have tangency
(indicating single point) on a single plane other than outside tangency?
Perhaps I missed something.  Just my 3.14... cents worth... ;-)
