Also, random access to disk takes a significant amount of time, so those extra 20 writes to disk would make the 6pc build much slower. And all this effort just to maybe gain a few percent on the time used to build the 7piece tables when we are finally ready to do that? Guess those weren't the thoughts you were looking forward to. Better luck with your next idea. Angrim
