Dear colleagues!
BOINC project for ODLS of order 10 started
https://boinc.progger.info/odlk/
Join the project!
Support the project with your computers.Thank you.
Natalia MakarovaPartecipanteA database of unique CF DLS of order 10 having orthogonal DLS
as of March 31, 2017 (38711 unique CF)Natalia MakarovaPartecipanteDear colleagues!
You can take part in the discussion of the BOINC-project Stop@home here
http://stop.inferia.ru/forum_forum.php?id=3You can also take part in the calculations.
Natalia MakarovaPartecipanteHere a database, obtained in my project (before the BOINC-project)
http://forum.boinc.ru/default.aspx?g=posts&m=86353#post86353Let me remind you:
my project “Symmetrical tuples of consecutive primes” started in forum dxdy.ru (Russia, 9 February 2015)
http://dxdy.ru/topic93581.htmlNatalia MakarovaPartecipanteDear colleagues!
The project «Symmetrical tuples of consecutive primes» changed the name and address.
See here
http://forum.boinc.ru/default.aspx?g=posts&m=86435#post86435The new address of the project
