See the CDB internal documentation at http://reality.sgi.com/pmk_craypark for CDB's internal 24-byte packed format, which is a hell of a lot simpler than this approach. The smallest context-free representation that I know of is 174 bits per position, but it would take way too much time to use in a real chess program. In a database where positions need not be context-free it is of course possible to get much smaller. Most positions in CDB 1.5 are represented by 12-byte structures, and in CDB 2.0 they're down to 8 bytes.
