Has anyone found a connection between prime numbers and Viswanath's constant? I believe I may have found a similar property, that the Fibonacci and Lucas...
Raanan Chermoni continues running my program and has just discovered another 17-digit AP23: 542440132260899 + 4560607*23#*n, for n = 0 to 22. It has the...

Sieving to depth around 5*10^15 for candidates with about 333,333 bits gives a Poisson mean mu = exp(-Euler)*333333*log(2)/log(5*10^15) =~ 3600 for the number...
... Never it seems ;-) I see this lofty entry from PrimeGrid: http://primes.utm.edu/primes/page.php?id=84745 uses David Underbakke's TwinGen. How much is...
... Ah, the doubly typomatic beast: 666,666. ... There is an initial penalty for David U's quadruple sieve, which soon dies away. Thereafter one may go as far...
Raanan Chermoni continues running my program and has just discovered two more AP24 (for a total of 5 known AP24 now): 515486946529943 + 136831*23#*n, for n=0...
... Congratulations! http://hjem.get2net.dk/jka/math/aprecords.htm is updated. After five AP24 at that size, it seems time for a AP25. Good luck! -- Jens Kruse...
4872^2 + 1 may be prime. (a = 2, err = 0.00e+000) 1*4872^2 + 1 : verification failed !? (a = 11) I was messing around with proth.exe and got this for a GF....
... The first time through is a probable prime test, all primes pass it, few composites do. Then a slightly slower definitive test is applied (verification)....
... Thank you for prompt updating. Well maintained website with results gives additional motivation for our work. ... Indeed, we have given up searching for...
Hi Jason, I haven't used proth.exe, but I think I can answer your question anyway. Your number is 4872^2 + 1 = 23736385 = 5 * 97 * 109 * 449, and hence is not...
... Thanks. ... Congratulations. I have updated again. You (alone or with Ranaan) are the only to find AP24 which I know is hard. But I wonder whether you...
Raanan's computers produced 7th known AP24: 1630799846252777 + 985151*23#*n, for n=0 to 23 It sets no record (although it has the largest known start). ...

Raanan Chermoni continues running my program and has just discovered 8th known AP24: 3120744164655323 + 851923*23#*n, for n=0 to 23 It sets no record (although...
David, have you taken a look at my findings on Viswanath's constant, that I sent you? Or are you kindly ignoring me. http://myspacetv.com/index.cfm? ...
... I had looked and thought that silence might indeed be kinder. However, since I am now asked in public, here is my response. Viswanath's constant is defined...
David you've got it quite wrong. You've failed to explain why you've imagined that characteristic words have anything to do with what I'm saying. Don't imply...
I didn't input the Fibonacci word to begin with. That was just the output that was observed. Are you assuming a fixed recurrence, with the disagreeing bits? ...
... But that was what told me that your conjecture concerned characteristic words, which are notoriously poor at delivering decimal digits. ... I did so only...
