Hello all,
sorry for bringing this up again, but there´s one more question about the v17 bug on
my mind and I don´t remember it being asked/answered before (I may have missed it).
Would a doublecheck with v17 on an exponent 4.2M result in the same (wrong)
residue as the first (wrong) test?
Hi everybody! The large amount of mail about assignments and
overdue exponents move me to check how things goes for me. I join GIMPS

I knew about it.

They seem to be developing a line of machines. I assume
the $1000 price is for the low-end machine and the 10^11
BIPS rating is for the high-end machine. It would be interesting
to see the BIPS of the low-end and the price of the high-end
machines.
