Prime Number Records

There are so many different projects searching for different types of record on the prime numbers front that it is next to impossible to try to keep a single page updated timeously. On this page I will content myself by directing the interested party to the specific websites most able to provide this.

For many of the tables, the Prime Pages Top Twenty Lists offer the most up-to-date data. However, there are frequently specialist pages that give far more detail into current search limits, those involved in searching, progress so far, etc.
