Anyone who isn't on the NMBRTHRY list will have missed the following interesting & relevant message: ------- Forwarded message follows ------- Hi all, We have published a new article : "An efficient probable prime test for numbers of the form (2^p+1)/3" Abstract : The developpement of a new probabilistic test for numbers of the form (2^p+1)/3, which have many common properties with Mersenne numbers. This test gave us probable prime numbers with an exponent p<400000 and confirms the "new Mersenne conjecture" with new exponents.
