Definition of colors and markings in summary tables:

k is 10^3 M is 10^6 G is 10^9 T is 10^12

Reserved Available

The Color of k indicates the different type of the number:
Low Weight k Riesel Number k 15k Candidate 2145k Candidate 2805k Candidate Primorial k*
* Primorial k: 13# means 2*3*5*7*11*13, that's the product of the first primes (abbrev. Pr(6)=first 6 primes)

Woodall primes are marked like this: 12345. (see overview here).
   (Note: 7911*2^15823-1 is also Woodall because it's the reduced form of 15822*2^15822-1 (only odd k)!!!)
Sophie-Germain-Primes: for one k, n and n+1 are prime, are marked like this 12345 (also called a Cunningham Chain of length 2 of first kind).
   (Note: three consecutive n like for k=3135 n=15,16,17 is called a Cunningham Chain of length 3 of first kind and so on...).
Twin-Primes: k*2^n-1 and k*2^n+1 are prime marked like this 12345 or if it is also Sophie-Germain like this 12345.
The 100th prime of one k is marked like this: 12345.
Numbers marked with 12345* got a comment for example see k=27291 (hold mouse over red star).
Nash-weight: standard for n=100001-110000.

ToDo:

  • Statistics with counting primes in ranges like twins
  • list Primorials with primes
  • fill more low primes (k's with text like "(60 primes 0-10k)")
  • 15k Search, archived forum

  • all relevant k*2^n-1 primes from Top5000 in here, actual id 1 to 1700 and from 77300 (13.03.2006) to 83111 (29.11.2007)
    checked/included (n with link to Top5000) (not included primes for n=333333 from PrimeGrid)
