I agree, of course. And besides, as Hyatt mentions, the best hashing scheme
depends on the hardware architechture. But the person who asked was looking for
a general answer, I think. One single answer even though no single answer
exists. That's why I wrote "best". But the best thing to do, sure, is to try
different schemes in ones own program.

P.S. The Breuker thesis that I've read (I know he has published 4-5 papers about
hashing), was definately not published in ICCA. It is a 100+ page thesis, and as
such too large for ICCA, I think.
