Excellent. It's nice to see the occasional <50% proof. Of course, it could just
try another witness, but it's much quicker to just perform the non-square test.

Thanks for the update, Bob.
In other news of closely-related projects, today I heard that one of the
old-school GFN project members had found _3_ large (400000-digit) primes in the
Extended GFN project that I created as the first offshoot of Yves Gallot's GFN
project before I created PIES, which was before LG, which effectively obsoleted
the previous extended GFN project. I'm just waiting for those primes to get
submitted, they'll all be top-100. It's a shame they weren't found as part of
LG, but never mind.

Hi,
I've completed my range as well, so I guess I'll reserve another range.
49152_k2_960000-970000.abc is complete, I've only found
Phi(49152,1869137652722) in it.
Hope to get another one soon again!

Client-server is still supported. Chris and I are still using that technique to
hunt for Apples.
For off-line processing, PIES reservations for Super-Peaches are here.
http://83.143.57.194:16384/makeres.cgi?proj=PIES&sp=49152_k2
Both are ~200000 digit candidates.

In simple terms, we've lost Daniel, which shrank us to a shadow of our former
selves, and on top of that, we're without Jeff, who was the other hefty
contributor when up at full speed. Add to that the fact that the 200000 digit
primes are hard to find, and our expectations become one every few months. I've
not found one for about a year. :-(

That's why I've been recommending super-peach and Apple searches only for quite
a while now, but respect individual freedoms.
Incidentally, apples are about to run out, and the next fruit up will come on
line - these guys will be _BIG_ :-), and of course, very rare :-(.

You'll not need all of those for daphisiv.
HOSTTYPE is just a name.

Hi,
I've completed my old range (49152_k2_950000-960000) with a total of 2
primes (Phi(49152,1812760323200) and Phi(49152,1837555687682)). I'm
now moving to the next range (49152_k2_960000-970000).
