Hi, I’m Michael Trofimov, the author of this preprint.Thank you for your interest, you are welcome to ask your questions. More info about me you can find, for example, in Intel site: http://software.intel.com/sites/blackbelt/hall_of_fame.php http://software.intel.com/sites/blackbelt/hall_of_fame.php (see Top Community Masterminds section). Is it self-promotion? ;-) Yes, I am not native English speaker, so I would be very thankful if somebody will mark unclear statements in the paper and will suggest his/her version. Very important: this is preprint only! It is not final result, the investigation is under the progress. During discussion in other web-sites and via emails: one minor bug in the proof and one bug in program had been found. The program bug was fixed, also some time later I will upload the second version of the paper to arXiv. All the best, -- Michael.
