Herbert, many thanks for all your work. Below are some brief comments on
your message about this.
I've updated my files as I've explained below. Should I send you a new
set?
Thanks,
Tony

Fine with me. I've renamed the file "arith.tex" too.

How about "is not a polynomial in its constituent kernels"?

You're right. I've moved it to algebra.tex.

algebra.tex
RESULTANT: please have a look at the TEX-parts: I think that
the 2nd polynomial should have a different degree (namely m
as in the INFO parts).
It is wrong. However,
the index on "a" should be m (as per Buchberger, Collins and Loos).

This was a bug --- I hadn't considered this in the new solvelnr module.

Now a question from me:
Should we move the single switch ADJPREC from "arith"
to "switch", or should we move some of the entries in
"switch" to other sections?
