Well Steven you just draw a line under connecting them all, and now you are allowed to call whatever combination you write down a single digit. And you have just created 429496729 unique symbols ;), in a pencil stroke. I know at least one intergalactic poster that will be impressed ;) -- https://mail.python.org/mailman/listinfo/python-list
