I think this job is a "not yet":
As we get more data from C200-C210 jobs, we will become better able to choose parameters and estimate relations-needed.
As GPUs with large memory become more common, we will have more matrix-solving resources.
In the short run, there are other more interesting numbers to spend our "team" resources on- such as 3,748+ that is just getting going.
Let's table this for 6 months or so.

Agreed. This is over 3 times harder than 3,748+ so let's get that done first.

Alternatively Ryan and Greg could probably factor this number in under 2 weeks if they want.

Maybe they already did, but don't want us to steal the downdriver

If someone felt like doing the polynomial selection, I'd probably be willing to sieve this.

Given how 2021 has gone 'round the forum, pretty sure that means you'll have a record-scoring poly within a month or so.

Edit: Helps if I scroll up and re-read to recall that there's already a strong poly for this, and it just needs test-sieving. I'll take that on, but not in the next few days.

Default C213 @ i2140

Would this be a candidate for another team sieve or left to the big guns?

My sieve/host resources are booked the next two months.

Sorry I forgot to build a params file for Ryan- I think I have time for that shortly, seeing as how I have two days left in covid isolation.

If you factored this 213-digit number, not only update the b-file of https://oeis.org/A008892 but also update the b-file of https://oeis.org/A347769, it is not known whether https://oeis.org/A347769 contains all nonnegative integers.

I am ready to give this number a go -- if someone has a good poly + params at the ready. (I plan to use the CADO siever, so CADO flags/params would be appreciated).

I believe the winning poly is here:

https://www.mersenneforum.org/showpo...&postcount=125

Don’t have a status on the parameters. Anyone got something?

I'll adapt the params from the last team sieve, the C207 Cunningham. I can get something posted tonight.

Ryan, this number is on the border of A=30 and I=16. Do you have a preference of which siever size to use? I=16 will use more memory, but a smaller Q-range.
