а) Пусть есть набор фигур полимино, каждая умещается в квадрат 10×10. Докажите, что если копиями этих фигурок можно замостить область, содержащую квадрат сколь угодно большого размера, то можно ими замостить и всю плоскость.
б) Существует набор фигур (уже не клеточных), каждая умещается в квадрат 10×10, копиями которых можно замостить область, содержащую квадрат сколь угодно большого размера, но нельзя замостить всю плоскость.

But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. The War on Fakes channel has repeatedly attempted to push conspiracies that footage from Ukraine is somehow being falsified. One post on the channel from February 24 claimed without evidence that a widely viewed photo of a Ukrainian woman injured in an airstrike in the city of Chuhuiv was doctored and that the woman was seen in a different photo days later without injuries. The post, which has over 600,000 views, also baselessly claimed that the woman's blood was actually makeup or grape juice. The regulator took order for the search and seizure operation from Judge Purushottam B Jadhav, Sebi Special Judge / Additional Sessions Judge. Perpetrators of these scams will create a public group on Telegram to promote these investment packages that are usually accompanied by fake testimonies and sometimes advertised as being Shariah-compliant. Interested investors will be asked to directly message the representatives to begin investing in the various investment packages offered. Some privacy experts say Telegram is not secure enough
