P₁ и P₂ - изогонально сопряжены в треугольнике ABC. X₁ и X₂ - проекции B на AP₁ и AP₂, а Y₁ и Y₂ - проекции B на CP₁ и CP₂ соответственно.
1) Точки X₁ и X₂, Y₁ и Y₂ симметричны относительно средней линии треугольника ABC. Если P₁ и P₂ совпадают (случай инцентра), то X₁ = X₂, Y₁ = Y₂ лежат на средней линии.
2) Обобщённые точки 255 лежат на хордах педальной окружности точек P₁ и P₂. Если A₁, B₁, C₁ и A₂, B₂, C₂ - проекции точек P₁ и P₂ на стороны BC, AC и AB треугольника соответственно, то X₁ ∈ A₁B₂, X₂ ∈ A₂B₁, Y₁ ∈ B₂C₁, Y ∈ B₁C₂.

In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. Official government accounts have also spread fake fact checks. An official Twitter account for the Russia diplomatic mission in Geneva shared a fake debunking video claiming without evidence that "Western and Ukrainian media are creating thousands of fake news on Russia every day." The video, which has amassed almost 30,000 views, offered a "how-to" spot misinformation. In 2018, Russia banned Telegram although it reversed the prohibition two years later. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. Ukrainian forces have since put up a strong resistance to the Russian troops amid the war that has left hundreds of Ukrainian civilians, including children, dead, according to the United Nations. Ukrainian and international officials have accused Russia of targeting civilian populations with shelling and bombardments.
