This site primarily lists prime constellation records. There are updated tables of the largest and smallest known
prime numbers in many different
patterns. A prime number is an integer which is above one and only divisible by
one and itself: 2, 3, 5, 7, 11, ...
The author is experienced in searching and collecting prime records. They are usually added within a day of being submitted here, or published somewhere on the Internet. Please mail any unlisted record you know about.
