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.
