    Why this matters

    the same math that sets the records

    Every record on a key-length number was set with the sieve and the curves running here. The numbers on this page are the open entries of the world's factor table: composites nobody had cracked. Each one we close is a real factorization added to mathematics, with the time and the factors on record.
