Absolutely. I hadn't even taken a good look at those datapoints yet. The dataset that I'd like to see: 000-000-0001 000-000-0010 (etc) 000-000-0002 000-000-0004 000-000-0008 000-000-0016 (etc) I also wonder if the last 8-16 bits involves, at least in part, a count of the length of the phone number, or at least a flag to distinguish 7 from 10 digits. -- http://mail.python.org/mailman/listinfo/python-list
