Let's see if I can say the same thing in different terms, for those (like me,
until I looked at the file) who might be confused:

1. Five plies are played from the opening position (White has finished move 3
but Black has not yet played move 3).  Snapshot each such position.

2. From that position, Black has a forced mate in 4 (or less).

3. Count all the possible positions from #1 that satisfy #2 and you get 5552.

Is that right?
