What's next?

So there's a few weeks left for current project.

Maybe we should do the top ten?

Of these, the first is being sieved by Bob Silverman and the second by NFSNET. Number 7 on the list was factored by Leyland & Wackerbarth on January 22

The others may still be available (I've not checked) but, unfortunately, most are too easy for us. We are already investigating possible follow-on factorizations.

so their list is slightly outdated...

this job is too easy to me, so I won't do it. LOL.
:D

but this can be fun, make all their top ten in a month or so. =)

but ofcourse it's all up to you. you decide.

There's a good reason for avoiding numbers that are too easy. It's the overhead involved. There are certain activities that take an essentially constant amount of human interaction, primarily by me and Wacky, irrespective of the difficulty of the factorization. Some other activities, such as the linear algebra, do depend on the difficulty of the factorization, but not by very much.

If, for example, each project took us 3 days to sieve and two weeks to do everything else, we would very rapidly become clogged by the non-sieving activity.

It's the supertanker problem. A supertanker is great for shipping a hundred thousand tons of oil halfway around the world, but next to useless if what you actually want to do is ferry a dozen cars over a strait twenty miles wide.
