Explanations
- In the beginning of the search in 2002 by Cletus Emmanuel the Carol and Kynea primes were searched and sieved individually. Later in 2004 Multisieve supported both types.
- End of 2004 there was a bug reported in the sieve program, resieving has to be done then.
- Historical data from the project page by Steven Harvey, some dates from The Prime Pages and Yahoo Group "Primenumbers".
