The result for 2,1642M should have been HARDER to achieve. It is 10 bits
larger than M811. I do not understand why their matrix was only 7+Million
rows, while that for M811 was 14+M. Further, they did the sieving in only 50
days with fewer machines. [although I suspect that they had faster machines].

Note that they used a lattice siever, not a line siever.

One of these days I will have to write my own lattice siever... [if I can find
the time!]
