BOINC-project ODLK1 continues to solve the problem of BOINC-project ODLK.
The project generates a database of canonical forms (CF) of diagonal Latin squares (DLS) of order 10 having orthogonal diagonal Latin squares (ODLS).
The necessary definitions for the theme can be found here:
New results of the ODLK1 BOINC project
The results of the ODLK1 BOINC project for March - December 2020 have been published.
See the topic
For March - December 2020, 2306590 unique CF ODLS were found in the project.
The processed part of the project database contains 11299868 unique CF ODLS.

Internet connection restored
So, the electrical power was shout down for 3,5h on Sunday in all the municipal area and the very good news was that the UPS (that was supposed to function for one hour) lasted for all the time and it was not near to finish the power reserve.
UPS is for saving integrity of server when there is no power, not to support all the rest of network equipments.
However when the power was back there were not internet connection!
As the service provider repeater is located 200m of distance and there were no workers on it (so all was supposed to be good), I contacted them soon for the problem as even their networks devices where in the area of power off so the problem could be here and/or there.
As it was Sunday their replay were at the rate of one in an hour and they let me makes lot of test until say at night that they will send a specialized technician to solve it.
I pass all the followed days to solicit intervention because the situation was critical for ODLK1, but it was in vain: assistance with ten-year customers proved to be practically absent!
Really unacceptable for a supplier who should guarantee a service that is always active 24h/24h!
This has now been, today they have restored the connection (it seems that the electrical works have damaged many devices throughout the area of 1Km^2).
I apologize for the situation but even replace the current internet providers will takes at least 20 working days, so the only solution was to attend their intervention.

Power off on 14/2/2021 for some hours
on 14/02/2021 from 8:30 to 12:30 (Rome time) there will be a switch off for current in my region.
Maybe the power supply will last for 1 hour, then the server will shut down until current return.

DB CF ODLS of order 11
I am officially opening a new project DB CF ODLS of order 11.
Some research on this project has already been done in the topic "ODLS of orders n>10"
Working theme created
Tomáš Brada helped me in my research.
See the topic "Diagonal Latin squares of order n>10"
The project has good software, which was created by Belyshev and Harry White.
At the moment I have a small database core containing 109025 CF ODLS.
I invite everyone to join the project.
I will consider your suggestions for launching a project on the BOINC platform.

DB CF ODLS of order 9
I am officially opening a new project "DB CF ODLS of order 9" .
This is not a BOINC project yet, but a manual project. I have been working on a project for a long time on a PC.
But you can turn a manual project into a BOINC project if you want.
Here you will find the software you need
(small archive, 2.1 MB)
The software was created by Belyshev and Harry White.
This is the script that works for me
@echo off DLS9R1BdFdCP.exe copy TemporaryDLS9R1BdFd.txt input.txt kanonizator_dlk9.exe < vvod1.txt copy output.txt input.txt ortogon_u.exe < Y.txt copy /b rez.txt+mates.txt rez.txt pause
