Planet Realmnoir uses the duodecimal system in its every day transactions. The federal government of Realmnoir has decided to issue new ID cards to its citizens. Under this scheme, each citizen will be assigned a different 10 digit duodecimal identification (ID) number. Any given ID number may contain leading zeroes.
For ease of record keeping, it has been decided that any two ID numbers must differ in at least two places.
What is the maximum number of ID cards that can be issued under this scheme?
