Wasn't me!

Is that how you say it?" There are other similar cases there. Surprisingly all "downdrivers" > 106 were quickly reserved by the yoyo server. That's a waste 'cause they will have duplicate calculations performed. For no reason whatsoever. Someone increased the search interval to 106+2000. Big mistake. (c)

It was me :) I need more sequences with composites < C130.
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 half of them 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.
