If you want to you can easily check things like that using a web-based service like: http://www.numberempire.com/primenumbers.php I have not verified if they have the ordenal you mention, but I am sure there are other web-services that can be used to verify that. I am not sure about what was your question, but please ask again if this was not an answer. Last fiddled with by aketilander on 2012-11-04 at 22:08

I'm not sure but using: http://primes.utm.edu/nthprime/index.php#piofx I figured out it's not primes with prime indexes ( though 5 of them seem to fit this, unless more do but I made an error.) as for if they are prime well you gave them a way to check.

 2012-11-04, 22:54 #4 aketilander     "Åke Tilander" Apr 2011 Sandviken, Sweden 10001101102 Posts So, using the webservice science_man mentioned I have now confirmed that they are all prime and they have the ordenal (are the nth) prime you mention. So your table is completely correct. I still don't know though what "the theorem 1379" is so maybe this is not an answer to your question?

I don't understand what it claims -- the text, as written, is self-contradictory -- but its form suggests that the numbers to which it applies should be close to a multiple of a prime to the power of 2698.

using: "theorem 1379" in google it gave back 18 results only 1 of which appears to not have something between theorem and 1379, but it's in a index part of the book so it means on page 1379. edit: oh and it hasn't even got that page in the book available, as far as I can see.

By googling 58426759 and 73278467, I found this page. The OP, that is also Arxenar, posted a link. Following the link, you can figure out what the "Theorem 1379" is.

Ah -- that only numbers coprime to 10 (ending in 1, 3, 7, or 9) can be prime, presumably with the exception of 2 and 5. But that's grade-school level, pretty far below the mersenneforums assumed level of competence.

 2012-11-05, 03:58 #9 LaurV Romulan Interpreter     "name field" Jun 2011 Thailand 3·5·683 Posts Ha ha ha! If my french (and google translator) does not cheat me, then this guy is don blazys in disguise. The name would justify it too, as is the same fire-related anagram (blaze, arson, I still believe the guy does this intentionally, as I can't imagine someone being so idiot). He claimes there that the 2^43112611-1 is prime or so, and when someone shows him that the exponent is composite (2671*16141) he switched his claims. If I understand right, the 1-3-7-9 theorem has something to do with the fact that all primes ends in 1, 3, 7, or 9 . (edit, crosspost with Mr. CRG) Last fiddled with by LaurV on 2012-11-05 at 04:02
 2012-11-05, 04:56 #10 CRGreathouse     Aug 2006 5,987 Posts I think of Blazys as being on more of a high-school level, so if this is him it's not his best work. But my French is pretty poor, so I can't judge if that's Don.
