Unreserving 136780

At index 689, with size 164 and a C159 cofactor ECM-ed to ~t53, and with D3 driver (2^3*3*5) we think it will not be of interest for some years to come. However some future interest may arise from the fact that this sequence is one of those which only went up, never down, from its starting, or when somebody will hammer the tail of Shai Hulud, working short sequences (due to the fact that this only went up, and the driver causes a quite fast growing, this sequence is one of the shortest to date...).

We will see... We added a lot of terms to it, since it got its driver, but now it is over our abilities, and the progress became too slow...

Edit: clarification, [U]there are[/U] shorter sequences, but they didn't reach so high, they may become longer when they will reach this number of digits

Somehow sorry to abandon a five-starter, but at index 5179, with size 165, it is going over my current abilities. With D2, i.e.2^2*7, plus some sticky 3 and 5, and a C150 cofactor ecm-ed to t50. Not of interest for the years to come (unless, hehe, Ryan or some other big gun gets angry with five-starters... :razz:)

At index 637, with size 164, D3, (2^3*3*5*C162), cofactor ecm-ed to t54. Not of interest for the years to come. Nurturing it from very early stage, but could not get rid of the driver.... Beware D3!

Sequences above 999,999 see far less work, and are unorganized as far as reservations go. You may work it, but no reservations are tracked for that range.

There are other similar cases there.
Surprisingly all "downdrivers" > 10[SUP]6[/SUP] were quickly reserved by the yoyo server. That's a waste 'cause they will have duplicate calculations performed. For no reason whatsoever.

The yoyo server doesn't duplicate calculations. It has a mechanism to detect that a composite is already in progress and doesn't sent it again.

If you want smaller composites, then we would have to extend the range of sequences. Extending it only to 1 002 000 seems quite silly to me, especially in such an ad hoc manner which introduces much unnecessary noise.

If you want to extend it to, say, 2 000 000 or maybe even 10 000 000, we can discuss that in another thread, which would also include much smarter ways to do said extension without introducing needless noise on the main webpage.

It is elementary, Watson!

Take all dangling C13X and C14Xs - there are absolutely tons of them.
ecm them very lightly - and almost [B]half of them[/B] will have p1X factors (this is checked on a few dozen unreserved sequences) - and Bob's your uncle! You will have hundreds if not thousands of C12Xs and C11Xs.

The three sequences 2664, 5352 and 9336 have christophe.clavier's name truncated by 2 characters. I haven't the faintest idea why that could possibly be.

It's because his name is too long for the reservation script and gets truncated. This has been the case since I added the reservations manually and is nothing to worry about.
