Group Description

This group is for discussion of the unsolved problems in number theory, logic, and cryptography which are featured on the web site


Problems include the Beal conjecture, the existence (or otherwise) of a perfect cuboid, the Collatz conjecture, the rational distance problem, the chromatic number of the plane, the discrete log problem, Grimm's conjecture, the ABC conjecture, Diffie-Hellman, the Goldbach conjecture, the twin primes conjecture, the Dorabella cipher (aka the Elgar cipher), the RSA challenge, the existence (or otherwise) of an odd perfect number, the existence (or otherwise) of a magic square of squares, Legendre's conjecture, the Riemann hypothesis, the Zodiac 340 cipher, and the Voynich manuscript, amongst others.

There are prizes of US$2,500 and a bottle of champagne on offer for correct solutions to many of the problems listed above.

The web site describes the problems and offers potential solvers the opportunity to have their solutions published, while this group facilitates questions and discussion.
