Could I please ask that everyone respects the right of George and Scott to be the first announcers, and to not jump the gun on this?

But, please, let us all make sure this is a well managed news release.

That is good to hear. I did not mean "made public" as in a press release, but that it leaked out to mathworld and such sites. I'm glad I was mistaken.

Well I'm not staying up to 1am. I guess I'll have some morning reading on Wednesday.

Here it is a counterexample:
http://arxiv.org/abs/1408.4505
http://arxiv.org/abs/1408.5110v1
the difference between the submissions is only one day. (it was a 10000$problem from Erdos.) 2016-01-18, 16:44 #293 rajula "Tapio Rajala" Feb 2010 Finland 32×5×7 Posts Quote:  Originally Posted by R.

Only a counterexample in the (quite insignificant) money-awarding sense. They were both received as original solutions and both were accepted for publication in Annals.

Doh! I totally missed that you had the exponent itself next to the link to that thread. Tunnel vision...

Here people in 2002/2003 are talking big about how fast their computers are now on the 16M-20M exponents compared to GIMPS beginning in 1996-1998: http://www.mersenneforum.org/showthread.php?t=188 http://www.mersenneforum.org/showthread.php?t=1556 I wish we could go back and tell them, that now we can double check a new 7xM prime in 33-36 hours on a Xeon, or ~56 hours on a graphics card!!! and we can factor a ~50M exponent to 72 bits in like 40 mins on a graphics card as well! Here is a major milestone, all exponents under 79.3M trial factored to 57 bit!!!: http://www.mersenneforum.org/showthread.php?t=336 Now think that people in 10-15 years might be reading this post (right now ;) ) and laughing at me bragging about these speeds. Now they can test a 150M exponent in 12 hours on their phones!!
