Before primes are added to the List of Largest Known Primes, they
must be first be verified, comments must be checked and they must meet the
size requirements. Below we show the
status of these primes (if any) that are awaiting verificiation (of any age) as well as those
modified (for any reason) in the last 72 hours. Click on the prime's id for more detailed information.
The color code is at the bottom of the page.

Note: Only proven primes are accepted
on this list. These colors refer the status of this list's (re)verification
process only.

We at the Prime Pages attempt to keep a list
of the 5000 largest known primes plus a few each of certain selected
archivable forms.
To make the top 5000 today a prime must have 421104 digits or meet
the size requirements for it's
archivable form. (Query time: 0.001946 seconds.)
