Re to Rene Grognard

I will geve a short answer to Rene Grognard, and to D.Tweed, since it is late and people will close the campus in a few minutes. Prof. Malaquias, from time to time, disappears. I do not know where he goes when this happens. However, he does not answer mails, and does not update his home page. Thi

Wow, thanks very much Simon! Someday perhaps maybe the compilers will be smart enough to take whatever crazy expressions I write and find the best way to do it :) Actually I am finally starting to learn a bit about the execution model so that I can try and optimize my code. Thanks again! +

Hi, having worked with some CA systems I want to add that not only the collection of algorithms is important but also the data base of algebraic objects. For instance the group theoretic package Magma (formerly Caley) comes with as much information on finite groups as the the libraries of algo

Ronald Thanks for your program, which had the amazing property that Hugs runs it 20x as fast as GHC4.05 -O! The reason turns out to be that you have hit on an optimisation that Hugs makes and GHC doesn't! But it is one that I don't expect to happen often enough to be worth adding to GHC. I'd
