I would hazard a guess that ECPP may potentially improve more than predicted over that time period. Currently development of ECPP software is restricted by a mess of patents. Speed should improve as those patents expire. https://en.wikipedia.org/wiki/ECC_patents

Also ECPP has never been truly exposed to distributed computing. This leads to any current records taking months on one pc to finish. If the same effort was put into ecpp as nfs factorisation then much larger numbers would be proven.

Can you publish on the list 5000 or even a topic that does not exist yet on the Top 20 the PRP 3 ^ 504206 + 2.

I'm sorry, Kebbaj, I'm not sure I understand the question.

The PRP is published on a PRP list here:

http://www.primenumbers.net/prptop/p...hp?page=3#haut

Currently ranked 542.

One of them expires today.

And it looks like most of the ones listed on that page are either expired or nearly so. The trouble is that there are probably more that we don't know about.
