Martin, I subscribed to the combinat list. I am also in the process of setting up an older machine which I hope will allow me to get an aldor binary running.
I will look at you code, and at the archives, and attempt to understand the issues involved. I have high hopes that we can enrich Axiom's abilities to describe mathematics.
