Hello, Group. Can someone calculate the length of N= (2^1660693)*(2^1660693+21)+1? I esimated it as [(2*1660693)*((log 2)/(log 10))] as someone suggested and...
... ? 2*1660693*log(2)/log(10) 999836.8131784078460461793726 ... My answer's very accurate, It appears that you've mixed 1660693 and 1660963. Phil () ASCII...

I think you can prove that Phil's example 103^16 is the smallest such number. Sigma(n) has factors (1+p+p^2+...+p^k) for p^k||n (<- largest power of p that...
... Yes, and you seemed to give a convincing argument. :) Did anyone notice that I basically gave away the key to finding Phil's example? I stated that...
The PRP's 10^19000+79387 and 10^19000-38663 produce a prime number GAP of 118,050 Milton L. Brown [Moderators note: Expected gap is ~43750, so this is ~2.7x...

I created a program that is testing for potential primes at 10^1,000,000,000+. My test yesterday was from 10^1,000,000,000 to 10^1,000,000,000+1,000,000 it...

... No, 'potential primes'. I can do that instantly by doing nothing. However, if I wanted to make use of a "small prime library of primes up to 1,000,000...
Is there a simple answer for the reason that ((2*T)^721) mod 115921 = 1 for all primes T except 13, 37, and 241 And, 721 =7 * 103 is the smallest such number. ...

I am not sure what you are saying, but ((2*2)^721) mod 115921 = 1 no? Also, ((2*3)^721) mod 115921 = 1 but not ((2*13)^721) mod 115921 =/= 1...
