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.

I have completed testing of new bases 401, 409, and 47616 all open sequences to >= 120 digits.

401^8 is an interesting one. It dropped all the way down to a value of 3086468 at index 1061 and 5...

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?

Karsten,

Reminder that I need primes for this range to update the reservation; or a statement that none were found.

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.

401^55, 401^63, 409^57, and 409^63 terminate

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!

As stated in the first post, the primes since your last status are needed to update the reservation -or- a statement that none were found.

The test depth cannot be updated without primes.

359^14 terminates!

That makes 3 terminations and 1 merge from the 120-digit effort. :-)

This one reached a high of 121 digits before its merge making it the highest opposite-parity sequence ever that I have terminated or merged. :-)
