Bases 251-500 reservations/statuses/primes

[gd_barnes]

Dmitry (unconnected) has R333 reserved to n=100K. After finding 2 top-5000 primes; he only has one k remaining at n=~90K.

[gd_barnes]

S470 is complete to n=25K; 2 primes found for n=5K-25K; 4 k's remaining; highest prime 91*470^6500+1; base released.

R334 sieve attached, no reservation.

25k-60k.
P=1.1T (1166975616589:M:1:334:258), over-sieved.

S266 sieve attached, no reservation.

25k-50k.
P=0.74T (740091963437:P:1:266:257), over-sieved.

(These are usually run over night, so progress is not checked until morning. Trying to keep my laptop busy on quick 64-bit work. Headers are posted here to keep a record of sieve depth; the header normally being changed for PFGW.)

What I usually do in such situations is use a PFGW comment, like this:

ABC $a*266^$b+1 // {number_primes,$a,1} //740091963437:P:1:266:257

That way, I can switch it into ABC format quite easily without losing the sieve depth data. Note from the above example that you can have multiple comments on the same line: I have verified that lines like that work in PFGW. (And with PRPnet, though I usually don't bother with the "number_primes" thing for that since it ignores it anyway.)

Ah thanks, I wasn't sure if that would work okay.

S263 tested to 100k.
Released.

Sieving for S259 should finish in a day or two.
