Definition of colors and markings in data tables

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

The color indicates the different type of reservation:
Done Reserved project Reserved person Available

The color of k indicates the different type:
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)

15k-, 2145k- and 2805k-candidates are indexed. So k15(1) => k = 15 and the index for a special 15k-value is calculated as
   (k + 15)/30 = index (for example k = 12345: (12345 + 15)/30 = 412). The same is done for the 2145k- and 2805k-candidates.
   The color indicates the type so k = 109395 is displayed as: 109395 (20)(26)(3647).

Woodall primes are marked like this: 12345. (see overview here).
   (Note: 7911 · 215823 - 1 is also Woodall because it's the reduced form of 15822 · 215822 - 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 · 2n - 1 and k · 2n + 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 and p < 511.

Low-weight k: all k's with Nash-weight < 1000 are marked as low-weight.
