License plates are issued systematically. In a state where the license plates contain three letters followed by three numbers, the following sequence of license plates could be issued: CMP998, CMP999, CMQ000, CMQ001, and so on. The most recent license plate issued in this state is AZY987, which has no repeated letters or digits. How many license plates must be issued after this one before a license plate will again have no repeated letters or digits?
Please show/explain each step!
Thanks!
