New SR5 Mega Prime!  |
|
On 19 June 2018, 09:48:29 UTC, PrimeGrid’s Sierpinski/Riesel Base 5 Problem project eliminated k=327926 by finding the mega prime:
327926*5^2542838-1
The prime is 1,777,374 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 60th overall. 71 k's now remain in the Riesel Base 5 Problem.
The discovery was made by Selya Tsuji (stsuji) of Japan using an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz with 32 GB RAM running Microsoft Windows 10 Professional Edition. This computer took about 43 hours 40 minutes to complete the primality test using LLR. Selya is a member of Team 2ch.

| Another GFN-262144 Mega Prime! |
|
On 17 June 2018, 15:40:35 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:
5205422^262144+1
The prime is 1,760,679 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 8th for Generalized Fermat primes and 60th overall.
The discovery was made by Scott Brown (Scott Brown) of the United States using an NVidia GeForce GTX 1080 in an Intel(R) Xeon(R) E5-1650 v3 CPU @ 3.50GHz with 32GB RAM, running Windows 7 Enterprise Edition. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL3. Scott is a member of the Aggie The Pew team.
The prime was verified on 17 June 2018, 16:44:04 UTC by Keith Reinhardt (Keith) of Canada using an NVidia GeForce GTX 1050 Ti in an Intel(R) Core(TM) i7-4790 CPU at 3.60GHz with 16GB RAM, running Windows 7 Professional Edition. This GPU took about 43 minutes to probable prime (PRP) test with GeneferOCL5. Keith is a member of the BOINC@Denmark team.
The PRP was confirmed prime by an Intel(R) Xeon(R) E3-1240 v6 CPU @ 3.70GHz with 2GB RAM, running Linux. This computer took about 5 hours 50 minutes to complete the primality test using multithreaded LLR.

| New graphs from 2018-06-14 |
Dear participants!
Next 5 types of graphs from orthogonal diagonal Latin squares discovered in RakeSearch project was published on preliminary results page.
[R9_000048091/02] - 2388 verticles and 7752 edges. Fourth graph with number of verticles larger than 2000!
[R9_000072907/01] - 18 verticles and 18 edges. Simple graph with "central square", "rim" and "stalk".
[R9_000072907/02] - 5 verticles and 4 edges! Tiny and very simple graph, but this is its first appearance!
[R9_000074356/02] - 26 verticles and 76 edges. Relatively small graph and second with 26 edges.
[R9_000076735/01] - 24 verticles and 73 edges. Another small graph and fourth with 24 edges!
When we move forward - we see a new structures, new types of graphs. And this is - a very interesting! Thank you for your participation in project, which made this possible!

| GDPR: restricting access to project statistics downloads |
Hi everyone, we'd like to announce that we're going to disable anonymous access to our project statistics downloads, becoming effective tomorrow, June 14th at 15:00 CEST. The reasoning behind this move is the new EU General Data Protection Regulation (GDPR) and its obligation concerning the publication of personal information of our users. We've discussed this matter with our community beforehand and found a way that seems to be acceptable for most. read more |

| Next 9 of graph types |
Dear folks!
The next set of graph types was published on preliminary results page! It consist of 9 samples:
[R9_000046266/01] - consist of 56 verticles and 360 edges. Verticles of this graph broken on core and two branches. Inside core we can see group of 16 verticles, located in "central circle", outer ring of another 16 verticles, and 4 verticles which a base for two branches. Each of verticle from "circle" linked with all 16 verticles from outer ring and 4 verticles from branch base but no any links exist between them! In consequence, each of 16 verticles of outer ring linked with all verticles in "central circle". Verticles in branches base - also.
[R9_000046266/02] - 78 verticles and 448 edges forms "arm" and "body" which are build from belts of verticles. Verticles in each belt linked with verticles in near belts.
[R9_000046269/02] - 32 verticles and 256 edges. Each verticle from rim connected to all vericles in center and each verticle in center connected with all "rim verticles". And no any links exist between verticles inside center.
[R9_000046269/04] - 16 verticles and 28 edges. "Ray-like" figure from two central verticles and three "rays" outgoing from them.
[R9_000046269/05] - 18 verticles and 40 edges. "Arm", "body", "horns". :) Unusual figure!
[R9_000047793/01] - 104 verticles and 644 edges. Interesting combination of two "belts" into "core", "rays" and "horns"! What is it? :)
[R9_000047793/02] - 80 verticles and 688 edges. Big insect?
[R9_000047796/02] - 28 verticles and 96 edges. Another challenge for naming!
[R9_000047796/04] - 16 verticles and 64 edges. Verticles in "central belt" linked with all verticles in left and right "belts".

| base R579 proven |
On 24th of May, JD2K, a member of the team Gridcoin found the last prime for base R579.
The prime 104*579^222402-1 has 614428 digits and entered the TOP5000 in Chris Caldwell's The Largest Known Primes Database.
Good job!

| Saturday graphs! |
Dear crunchers!
On preliminary results page we publish a next 5 types of graphs discovered in RakeSearch project:
[R9_000043841/01] - 8 verticles and 9 edges. Simple and symmetrical graph!
[R9_000044083/02] - 212 verticles and 1104 edges. Fourth by number of squares on today. We see a many "petals" - they corresponds a set of squares, each of them is orthogonal to 2 other squares, "located" in center of "flower".
[R9_000044085/03] - 56 verticles and 400 edges. Flower in a pot?
[R9_000044623/01] - 38 verticles and 106 edges. Can any to invent a name for this figure?
[R9_000045135/01] - 37 verticles and 97 edges. Crab? Fish? Flower? Alive? Not?
Thank you for attention to project and donation of CPU time!

| "Are we alone?" on VICE |
The HBO series VICE will be broadcasting an episode with a segment entitled "Are we alone?" starting June 1 at 11pm EST. It will be available on HBO streaming service, HBO GO, at 7:30pm EST.
The segment includes interviews with the father of modern SETI, Frank Drake, and a SETI@home volunteer, John Fluth, who has been a part of the project nearly as long as I have. We'll be interested in seeing your reaction to this piece.
Trailers are available through facebook and twitter.
The full episode is now available on dailymotion.

| Sunday graphs! |
Dear participants!
On preliminary results page a new 5 types of graphs, discovered in RakeSearch project, were published.
[R9_000042319/01] - consist from 28 verticles and 79 edges and near to figure with radial symmetry.
[R9_000042871/02] - drafted by 68 verticles and 146 edges. A fish from seabed?
[R9_000043553/02] - crayfish from 28 verticles and 80 edges?
[R9_000043575/02] - looks like chrysanthemums on stems and this graph is significantly larger than previouses in group - 132 verticles and 320 edges forms it!
[R9_000043575/03] - a relatively simple graph, only 14 verticles and 27 edges. Stops and routes of urban transport? :)
Of course, no any sense in this figures exists and "fishes, flowers and satellites" - just for fun (it's a weekend pictures!). And using another method of graphs layouting, we can get absolutely other visible form for it. But human mind, targeted on recognition of known objects in lines and spots - will see still some figure.
And we congratulate a Daniel from BOINC@Poland (or [B@P] Daniel) with the first place by total credit!
