Unreserving 383082 952320

I suspect that someone else is calculating these two aliquot sequences.

yoyo · 2017-10-26, 18:20

I'll take them and additional 100 sequences with length 139 :)

There is somthing new cooking at the AllSeq web portal, with sequences above 10⁶ showing up now.

Code:

Sequence	Size	Index	Guide	Known Factors	Cofactor Size	Class	Last Updated	Recent Progress	Reservation
1000564	123	3277	Downdriver!	2 * 19 * C122	122	1	2017-10-31 15:27:54	3278

702688	148	756	2^9 * 3 * 31	2^9 * 3 * 31 * C143	143	2	2017-10-31 11:48:05	2017-10-19	
1000126	188	3335	2^9 * 3 * 11 * 31	2^9 * 3 * 11 * 17 * 31 * 1871 * 281069 * 565985201 * C164	164	0	2017-10-31 14:31:36	3336	
1000516	188	3350	2^9 * 3 * 11 * 31	2^9 * 3 * 11 * 17 * 31 * 1871 * 281069 * 565985201 * C164	164	0	2017-10-31 15:23:57	3351

...

Note that 1000126 and 1000516 are both obviously merged into 7044.
1000946 is merged into 219804
1000288 is merged into 118020, etc...

Unclear what the purpose of this experiment was.

"That's a bingo! 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.

BTW: We should lead this discussion in a separate thread.

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.

Let's discuss about enlarging the reservation page in this thread: http://www.mersenneforum.org/showthread.php?t=22680
