I agree, that it is a trivial trick. I did not know, that it is old. I have no
doubt, that many people would have thought about it, and come up with it. When I
told it to other chess programmers, none of them seemed to be aware of it,
however. You might even see often the argument of "mod is too slow" in the
history of CCC positings, without mentioning the possibility to avoid modulo and
still to have an arbitrary number of hash entries.
