Пусть есть три натуральных числа (a,b,c). Построим новую тройку: минимальные натуральные (x,y,z) = g(a,b,c) такие, что xa=1 mod bc yb= 1 mod ac zc=1 mod ab (а если таких нет, то g не определено)
Эту функцию g можно итерировать, например, g(3 5 7) = (12 17 13) g(12 17 13) = (129 101 157) g(129 101 157) = (1598 8021 6556) и дальше не определено.
Обычно заканчивается за несколько шагов, хотя и очень быстро растёт. Для 3 5 11 довольно долго живёт:

Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe. Ukrainian President Volodymyr Zelensky said in a video message on Tuesday that Ukrainian forces "destroy the invaders wherever we can." "Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." "There are a lot of things that Telegram could have been doing this whole time. And they know exactly what they are and they've chosen not to do them. That's why I don't trust them," she said. The S&P 500 fell 1.3% to 4,204.36, and the Dow Jones Industrial Average was down 0.7% to 32,943.33. The Dow posted a fifth straight weekly loss — its longest losing streak since 2019. The Nasdaq Composite tumbled 2.2% to 12,843.81. Though all three indexes opened in the green, stocks took a turn after a new report showed U.S. consumer sentiment deteriorated more than expected in early March as consumers' inflation expectations soared to the highest since 1981.
