Subproject #3: 700k-800k sequences to 100 digits

[RichD]

I'm still running the 783750 sequence. It has been real slow lately with the composite growing one in size each day. The current driver is 2 * 3 and size of c97. It should be complete in the next 2-3 days.

Edit: Just crossed into c98 territory.

Sequence 792390 is broken at index 1660. An 80 digit number is marked prime, but is factored in the sequence.

Is there anything we can do about these false primes? They suddenly seem very common. Is Sid the only one that can fix them? We need a repair on the factor page to recheck primality or allow one to test factors.

792390 is at 113 digits with 2^2*3*7

794754 finished: size 103, i1020, 2² * 7 * 11 * c103

db corrupted, elf attached, iterations have been uploaded to db

Again a sequence which reached index 4000...

Index 4091 (started at index 1242);
Size 110;

Driver: 2^2 * 7

790620 complete: size 100, i 1126, 2^4 * 3 * 7^2 * 31 * c95

Reserving 790560

For info, 790340 was vandalized by setting the last term (which is even) to prime.

Done with 783750 sz 100; 2 * 3 * 7 * 17 * c97
(results are queued up via Report Factors).

Reserving 791982

794304 is finished, size 100, i1046, 2 * 3 * 31 * 67 * 3163 * 1726009 * c86

Reported to db, but the sequence didn't update yet. I'll add the elf here later, if necessary.

BTW, I did move the sequence a couple lines by adding the large factors manually, but it still didn't catch the update. I'll check again later.

reserving 794184

Of note: aliqueit says the c81 factor in iteration 1183 is not prime.

I've removed i1183 and i1184 from my elf file and started with i1183. I suppose I will just post my elf file here when finished, unless the db has been corrected.

update is online

i've tried to mark corrupted seqs with error, but it's possible there're more in the DB.

to everyone: please check the Summary-700k-page for reserved seqs <770k.
there're some seqs not yet unreserved or i'm not aware of it.

794016 appears finished in the db

I have finsihed 794340 as well, but the db hasn't updated, even though I uploaded the new lines last night. I will post later with the details.

Indeed it is. I even double checked its integrity with aliqueit, all's good. Removed from list of available sequences.

The database has a ton of work queued up. Perhaps it just hasn't got to your lines yet. In any case, it's probably safest to post the elf, like you said you would.
