If that doesn’t crack it, perhaps go to up to (2x) 9900 curves @B1=29e8? Yoyo can handle B1=76e8 as well, though progress at that level is VERY slow. I’m not sure what the max number of curves per pass, perhaps 5000? This is a huge job. The above ECM work will take months.

Wow, thank you! That should be enough ECM to move on to GNFS...
Is there any chance you'll run the GNFS yourself? If not, it should be within range of NFS@home if Greg is happy to queue it, though of course that requires finding a polynomial first.

This poly search will be “challenging”. I’ll help but it will take a group effort. And Gimarel, who has found many record polys, is on a hiatus until the hot season passes.
Maybe we should wait on this search until autumn? Just a suggestion.

I'll be doing a couple weeks of CADO poly select on this, starting midAugust.

How are group poly searches organized? If someone could walk me through it, I'd gladly participate.
