COMMENTS

This sequence is presented by the Foo Bar Challenge, a recruitment tool for Google, as the challenge to renumber some entities with 5digit ID numbers taken from the first 10004 places of the CopelandErdős constant.
The ID numbers are to be left zeropadded as needed to ensure they all consist of five digits. Of course here in the OEIS leading zeros will just be dropped.
The Foo Bar Challenge statement of the problem says nothing of the fact that there are duplicates among these well before 10000.
