Fischer Random Chess has the 960 legal starting positions numbered, and has
the details on how to find a position from it's number, and how to find
the number based on the position. Capablanca Random Chess could benefit
from such a system. Besides making it easier to identify starting
positions, it would also solve Fergus' present dilema. If a position can
be determined from a position number, all that would be required is
generation a random number in the valid range.
For a good description of how FRC identifies positions by number, see:
