# Prime Verification Status

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.

#### Legend

Prime Description Color Codes |

Composite | Proven composite |

Remove | Scheduled for deletion because it is too small or proven composite |

UnTested | Not yet tested |

InProcess | Currently being tested |

Probable-prime | Shown to be a PRP,
awaiting further testing (see note). |

Proven | Proven prime |

External | Proven prime, externally verified |

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

Rank/Id Color Codes |

short | On the short version of the list |

yes | On the long version of the list |

no | Not on the current list |

(unknown) | Not yet re-ranked |

Note: This list is (re)ranked every 30 minutes. |

Description Notation |

\ |
back-quote (23\ 45 = 2345, used to allow long integers to line wrap) |

# |
primorial (9# = 7*5*3*2) |

!, !_{n} |
factorial,
multifactorial |

Phi(*n*,*x*) |
*n*th cyclotomic polynomial evaluated at *x* |

We at the PrimePages 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 490226 digits or meet
the

size requirements for it's
archivable form. (Query time: 0.002603 seconds.)
