Well, that wasn't enough for my Maple Version

                     Maple 6
                   Jan 31 2000

(Hmm, I thought it was Maple V. And maybe it's just Maple V, R6?).

It gave a clear 0 for check #4 and #5 (great! thanks!), but
it failed for #3 and #6. Following the advice of my nephew
Frithjof I combined all the tricks:

convrad := x -> convert(x,radical);
squeeze := radnormal@expand@evala@Normal@simplify@convrad@simplify@f@simplify;

And, alas! There we are:

map(squeeze,p);
                          [0, 0, 0, 0, 0, 0]

What a neat result! Many thanks for your help. That was fun!

Cheers,
Rainer
