Yes. I guess my concern was to ensure that whatever was written, was
legally covered by the GPL. I'd hate it to fall through a crack on
account of me having not made attribution by the legally accredited
technique.

I see. So copyright is kind of cummulative.

Thanks. I noticed it had disappeared from the road map, and wondered
about that.

I had planned to sort that out for you, this weekend. I sped it up more
on SAGE by the way. It now runs at the same speed as on my 2 GHz
Athlon, and that is with a highly questionable GMP installation that I
am linking it with.

I was going to write primality testing, trial factoring, power testing
(which are all easier than I thought) and combine with GMP-ECM *and*
run some very important tests, and sugar coat the output ready for use
in SAGE, this weekend. But unfortunately two very, very nasty bugs in
my Schoenhagen-Strassen code kept me working on that instead. David
Harvey found one bug, the other took me a whole day to dig out.... Next
weekend perhaps!

Bill.
