Придумал формулу. Знает ли такую человечество? Суммирование по всем парам целочисленных векторов x, y из первого квадранта, таких, что натянутый на них параллелограмм имеет ориентированную площадь один.
Я вот не нашёл такого нигде. Доказательство, впрочем, вполне школьное, в три строчки, может её и придумывали сто раз.

Members of the public who suspect that they have been approached by unauthorised firms or individuals offering schemes that promise unrealistic returns Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. The last couple days have exemplified that uncertainty. On Thursday, news emerged that talks in Turkey between the Russia and Ukraine yielded no positive result. But on Friday, Reuters reported that Russian President Vladimir Putin said there had been some “positive shifts” in talks between the two sides. As a result, the pandemic saw many newcomers to Telegram, including prominent anti-vaccine activists who used the app's hands-off approach to share false information on shots, a study from the Institute for Strategic Dialogue shows.
