I have completed testing of new bases 419 and 421 all open sequences to >= 120 digits.

All bases > 350 are back to complete to >= 120 digits.

It looks like you got all of my testing to 120...

421^57 terminates

419^63 is released. Full ECM on the C152.

I'm done with new bases 419 and 421.

Only 1 sequence remains on base 421.

Nice!

That's termination #22 from the index 1 effort and the first one in a while.

I'm still working on 419^63 and 421^57.

I'm done with both exponent 65's.

For new bases 419 and 421, I'm beginning work on all same-parity exponents > 48.

Suggestion for you, Ed: 39^99. This one popped up after you cracked it on the index 1 effort several days ago. ...

317^8 merges at index=2830 with 36468:i22.

Now 4 terminations and 2 merges for the 120-digit effort.

You updated a few hours too early. When updated, base 313 was down to 2 sequences remaining to have all at >= 120 digits.

Now base 313 is complete to >= 120 digits. :-)

I'm a little confused...

Ed is going to run base 103 to >= 120 digits.

That works well. It would have been ~5-7 days before I started on it.

With nearly 1M tests, the file would be too big for Yoyo.

The file that is posted on the reservations page is sieved to 1e14. I assume you must have sieved it further.

A couple of questions to keep my spreadsheet current:

Are all of the C153s now ECM'd to t50?

Have all of the ones that were added from new bases 47616, 1305184, and 1727636 been ECM'd to t50?

47616^36 can be added.

It was ECM'd to t45.

I worked all of the untouched exponents on the 3 recent new bases. This is the only one that still remains at index 1.

I'm done with the same-parities on bases 401 and 409.

Only 1 remains on both of the bases; exponent 65.

These were most excellent bases!
