Second half of 54.4M

Now "reserving" for 30 days all the exponents in
the second half of 54.4 M
that has B1=B2≤730,000 [B]and[/B] without a DC.

Currently working on:
- 54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000)
- the whole 54.4 M (B1=B2≤730,000)

[QUOTE=Ensigm;562166]Cat 1 exponents with only Stage 1 P-1 are surprisingly rare. I'm now "reserving" for 30 days all the exponents in
- 54.36 M, 54.37 M, 54.38 M and 54.39 M
that has B1=B2≤730,000 [B]and[/B] without a DC.

These "reservations" only apply to factoring.[/QUOTE]

In many of the 5xM, 4xM and 3xM ranges they will be rare because of the work I (and others) have been doing there the last 3 years working on the sub-2000 project here:

In short the goal is to get all 0.1 Million ranges to below 2000 unfactored exponents.
For example here 39.3M and 39.6M are the ranges not below 2000.

We achieve this by more bits of TF and deeper P-1 especially where B1=B2 or they are relative low.

First half of 54.5 M

Now "reserving" for 30 days all the exponents in
the first half of 54.5 M
that has B1=B2≤730,000 [B]and[/B] without a DC.

Currently working on:
- 54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000)
- the whole 54.4 M (B1=B2≤730,000)
- the first half of 54.5 M (B1=B2≤730,000)

Previous ranges 54.36 M, 54.37 M, 54.38 M, 54.39 M (B1=B2≤730,000) should now be finished and I am "unreserving" them.

Report for the whole 54.3 M:
5 factors found in 81 attempts (6.17%). Based on the bounds that were used, expected probability would be between 3.78% and 3.81%.

Currently working on:
- the whole 54.4 M (B1=B2≤730,000)
- the first half of 54.5 M (B1=B2≤730,000)

Second half of 54.5 M

Now "reserving" for 30 days all the exponents in
the second half of 54.5 M
that has B1=B2≤730,000 [B]and[/B] without a DC.

Note: this will be the last range I take in Cat 1 for a while. I will be going on a vacation shortly, and my maximum throughput will decrease by about 2/3 and will also become less constant. As a result, I will be moving away from smaller exponents so that those with higher throughput may take them.

Currently working on:
- the whole 54.4 M (B1=B2≤730,000)
- the whole 54.5 M (B1=B2≤730,000)

When you are done there could I interest you in bringing that kind of P-1 power to these ranges to help with my sub-2000 project:
48.4, 49.6
It's just over 1,500 exponents with similarly low B1=B2

And if that's not enough I can find more.

Thx

I will probably first go over all exponents under M48 with B1=B2<700,000 and no DC. That's gonna be at least until this year's end. Then I will either go into sub-2000 project or "regular" first-time P-1, or do both.

Also don't think that is lots of P-1 power. I'm currently just over 120 GHz-d/d and will soon go down to around 40 GHz-d/d. If you have over 1,500 exponents spread in 2*0.1M ranges I will probably take only 0.01M at a time.

Second half of 55 M (B1=B2≤690,000)

Now "reserving" for 30 days all the exponents in
the second half of 55 M
that has B1=B2≤690,000 [B]and[/B] without a DC.

Currently working on:

First half of 56 M (B1=B2≤690,000)

Now "reserving" for 30 days all the exponents in
the first half of 56 M
that has B1=B2≤690,000 [B]and[/B] without a DC. Will also try to reserve them as TF assignments.

[STRIKE]Previous ranges 54.4 M (B1=B2≤730,000) should now be finished and I am "unreserving" them.[/STRIKE] Edit: one exponent 54482819 still remain WIP.
