OK, the server is running and the scope of work has been decided. Of course this is the moment when a totally different thought pops up :razz:

I am working on R48 and will take it to n=100k. As there will be more than 25 k's left at that point, I expect it to be discontinued. I just can't imagine there to be many people willing to bring 25, 100 or 200 k's to higher n levels. With a distributed effort it might be manageable. The chance of proving such a conjecture is very small of course.

Still, when I look at the reservation pages I keep seeing those (rather) low base conjectures that have been started but probably won't be worked on for years because it's too much for an individual. Wouldn't it be nice to get some of those to n=100k (or maybe higher)? I'd be willing to do some sieving.

Just a thought.

I just did one final check over all of the bases <= 200 and it appears that we missed one; S70. Therefore:

Adding S70 to the drive with 5 k's remaining at n=100K.
