text: Bah, I'm not interested in theories... But maybe you've also found a way to construct them quickly? I hope these Energizer bunnies at mersenne.org can stop now and relax a little :)\n\nupd: pardon my English, it's not my first language. By "theories" I meant "theoretical issues" including theorems of low practical value, e.g. FLT. \nIANAM, but I think a constructive proof would be really big... However, on second thought, even a constructive proof would hardly be useful/disturbing for cryptography. Better focus your efforts on fast factorization ;)
