Tritium is no longer used. Check out the price per gram in the following link.

http://forums.timezone.com/index.php...91#msg_5385799

Luminova is what is used now.

http://www.umccorp.com/luminova.htm

Tritium has the advantage in that it glows* all of the time, until the radiation decays. Luminova glows brightly, especially when exposed to sunlight, but it wears out in an hour or two. It glows dimly longer and if your eyes are adjusted to the dark it is readable, but it is still very dim.

There is a chain of restaurants near us that is called "Panera Bread". They are pronounced pah-nere-ah. We think, from the recording linked earlier, that Panerai is pronounced pan-er-rye.

However ET_ lives in Italy so we think he knows a lot more about this than we do.

* Tritium does not glow at all. The radiation it produces causes another substance to glow.

I must admit that my phonetics were biased by how Italian language is usually spelt outside Italy. Mike seems to be right, though I'd put one less "r", and the tonic stress on the last syllable...

My mom's computer just found a 126-bit factor, which I thought was pretty cool:

Quote:
[Fri Dec 10 16:53:48 2010]
P-1 found a factor in stage #2, B1=620000, B2=14880000.
UID: ixfd64/chiousheng-pc, M53384579 has a factor: 159300289520716781055019313575833719369, AID: 57543D385CE567B69A14C08F596AC9B4
It's prime, too!

Very impressive. I've been doing almost exclusively P-1's for several years now, and the largest prime factor I've found is only 104 bits.

k = http://factordb.com/index.php?id=1100000000263838823
Even at that size, the bounds were much higher than necessary! B1=90K and B2=6.3M would've been sufficient, and your bounds were B1=620K, B2=14.88M. Nice find.
The probability that your P-1 would find a factor of that size is between 0.0051 and 0.00059, closer to the latter (those figures are for 35 and 40 digits, respectively, with almost-identical B1 and B2 bounds, from ecm -v; this factor is 39 digits), or close to 1/1500. The probability of finding a factor that large and that smooth is closer to 1/10000.

I have a naive and most probably stupid question:
Does Prime95 preload with group order p?
Does this help (or would this help)?
E.g. here, P-1 = 2 * 2 * 2 * 17 * 2963 * 8707 * 29473 * 51511 * 89387 * 6267047 * 53384579 (where p is the largest factor and is ab initio known).

P.S. Yes, it sure does. Tested:
Pminus1=1,2,53035711,-1,1700,21000
=>
P-1 found a factor in stage #1, B1=1700.
M53035711 has a factor: 61678157492310549218180505113
