Nice, I realized after I posted my 2nd solution that it was missing some cases and it's good to see confirmation that 239 is reachable. I'll see if I can fix my version. I think the list copying is ok given that the recursion depth always must be fairly small if the generator is to complete in any reasonable amount of time. -- http://mail.python.org/mailman/listinfo/python-list
