The goal and level of this collection
Our goal is to create a collection (a dictionary if you will) of individual prime numbers with interesting properties or forms. So just what is exciting about the prime 313? What might we discover about 9999999900000001? Since the number of primes is infinite, we can not list them all; but we can list the small ones that are especially curious.
Do you know an interesting number we should add? Can you explain your curio in a way that would be understandable to a general audience? In a tone that would make others want to hear more? If so, let us know.
Can you find the first missing prime curio?
There are currently 18586 curios corresponding to 12946 different numbers
in our database, that leaves an infinite number for you to discover! Database last
