96^81 gave an interesting split: c153 = p50 * p51 * p53

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?

Yes, for the new bases (all four in three bases). The c153s are in work.

Now everything > 150 digits has been ECM'd to t50. Several broke.

OK, all cofactors have had t50 ECM.

40^106 has advanced.

ETA: And so has 55^94.

ETA2: 63^97 has advanced.

Yoyo confirmed that they do not work on cofactors > 139 digits per this post:
https://mersenneforum.org/showpost.p...postcount=2113

It appears that all reservations shown in the 1st post here are Yoyo reservations. Since the smallest factor here is 150 digits, I feel like all of those reservations can be removed.

This actually explains something that I had been wondering about. I had noticed how some of the same-parity sequences would advance 1 index out of the blue and that those sequences were usually on bases that Yoyo had reserved and the cofactors cracked were always < 140 digits. This occurred even though the specific same-parity sequence was not shown as reserved, likely due to the assumption that Yoyo only worked opposite parity sequences. I would then wait for several weeks after the single index advancements to see if they were still being worked and noticed they never advanced again (due to a new cofactor at > 139 digits). Strongly suspecting that no ECM had been done on the next index, I then picked them up myself and confirmed as much. I often advanced them several more indexes and sometimes terminated one.

The bottom line: Yoyo will work on same-parity sequences on bases that they have reserved but only if the cofactors are < 140 digits. Since the smallest cofactor that we have now on same parities is 136 digits, those advancements are fairly rare.

I now know what to watch out for on Yoyo bases: Any sequence where the cofactor has reached >= 140 digits regardless of its parity. At that point, it is safe to assume that they have been released.

You can see all sequences on which my volunteers are working here https://yafu.myfirewall.org/yafu/dow...tSeqences.html .

Should I use this page to flag reservations, rather than the earlier supplied ali.txt.all or flagging all of a base that has been claimed in the n^i thread?
