I would like to unreserve any sequences I was working on if this hasn't been done already

The computer I was using died badly a while ago. I lost the address of the forum, but suddenly just...

My sequence checkin has reached 7 million taken to 80 digits. I was originally going to do 60 digits but it looks like I can do up to 80 without slowing down my rate of adding numbers to the DB.

Issue with gnfs failing to proceed.

I seem to have had an issue with gnfs/msieve getting permanantly stalled while trying to get the total yield. I tried deleting the ggnfs directory, but I think it happened again. Is there a...

Sequences from the 5 to 10 million range

I have been working on range from 5-10 million. I started this to answer the question whether there are any longer cycles to be found. Sequences below a smaller maximum have already been searched,...

I think the solution is to give credit for finding a termination to whoever has it reserved since they were going to find it anyway. That way there is no benefit to running someone else's sequence...

I noticed two issues when getting some aliqout seqs. These are lower priority as they are for non-open sequences.

There was no test.job so I tried running it again. For some reason (aliqueit may have done something) it started with a new polynomial search.

I then didn't get the same fail - it appears to...

Infinite loop for ggnfs or msieve

I have an infinite loop. The output on the screen is given below. I tried deleting the ggnfs directory and restarting but it sill got stuck.

Would this be an issue with the version of ggnfs that...

Could use some scripting help (windows)

Currently, I have a very primitive way of submitting sequences to the database (this is a *.bat file on windows). For example:

aliqueit -s 0 6261388
aliqueit -c 60...

It appears you are using the full power of the odd prime exponent when calculating class. That is why you get a class of -3 for 2*3^7 term.

The 7th power isn't supported by the 2 so I would...

2^2*7 makes sense as the most common, I think. 2^2 is fairly common to hit and it isn't hard to get a factor of 7. 2*3 is harder because the 1st power of 2 is harder to get, and 2^4*31 is harder...

2^2 has been called the down guide (its not a driver) but I think its more the 'stay the same guide'. It pick up and loses the 3 or 5 to alternate between rising and lowering. 2^2 is hard to lose...

Just a comment, If the power on the 3 is higher than 1, then I usually don't consider it a driver, though the definition doesn't cover this case.

The reason is that 2^3*3*5 has 2 powers of 3...

Not completely sure if this is similar:

The expected number of factors for a number x is ln ln x. So if we have a number like m=7 (a prime is simpler) it will not appear in the sigma if all the...

At 130 digits, 2^4*31 would have 1/430 chance of escape.

It occurs to me another definition of a driver could be based on whether the b from a+bx is greater than or equal 1, rather than the 2...

Made an April version so this is from last week.

It also includes a column of the factors known in the DB, so you can see what the current driver is.

I had to zip it to make it fit.
