Hi Daniel -

Not sure what isinteresting about this. I haven't the foggiest as to  
how to find the result which to me, would be interesting.  But maybe  
I'm not doing it right.

What I DL'ed had to be run in Terminal mode. And after some fooling  
around I discovered that parameter = 21 gives the 22097152 figure.  I  
discovered that that is =2^21.  Anyhow FWIW,  my stock iMac G5 2.0  
GHz seems to get done in 100 seconds.


Here's a copy of the output.
