Statistics of the Data-Section

Started: Sep 13, 2007
Last update: Nov 30, 2007

Ranges as follows:

A: n<10

B: n<100

C: n<1000

D: n<10000

E: n>10000

Data for twins from gd_barnes and Citrix here (all twins for k<100000 and n<15k)
Note: Only on summary-pages marked twins or CC's are counted so if anyone finds more, please contact kar_bon.

Other Stats:
listed Woodall primes : 32 (all known so far)
checked primes of TOP5000 : 7500 out of 83111 (30.11.2007)

ToDo:

count primes in ranges

remarkable spots of this table as example like CC6 for k=45 or 8 Twins for k=165 and 1995
