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