Anyone else expecting a new prime 19tuplet?
Looks like someone is really out to get the first "big" prime 19tuplet: http://anthony.d.forbes.googlepages.com/ktuplets.htm
I've been waiting for this ever since these two 18tuplets were discovered in 2000/2001. Anyone interested in predictions? Mine: late January / early February this year. Also, did anyone attempt to find a 19tuplet themselves? I did, but I only invested about 150 hours in a calculation that would surely have taken the best part of a decade to actually find one...

I don't know.
I used my own BASICprogram, presieved m's to 37# or thereabouts, looked for small factors up to 73, then searched values of k*73#+m for further factors up to a given point in a given range for k, proceeded by quick PRPchecks. I think it's about the best you can do. Last fiddled with by mart_r on 20090113 at 19:46

There are two 19tuplet searches. Joerg Waldvogel & Peter Leikauf who found the first two nontrivial 18tuplets have been searching a 19tuplet for years: http://www.sam.math.ethz.ch/~waldvog...clprimes05.pdf.
Jaroslaw Wroblewski started a search 4 December 2008 and has found two 18tuplets: http://tech.groups.yahoo.com/group/p.../message/19760.
