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, which does little policing of its content, has also became a hub for Russian propaganda and misinformation. Many pro-Kremlin channels have become popular, alongside accounts of journalists and other independent observers. "And that set off kind of a battle royale for control of the platform that Durov eventually lost," said Nathalie Maréchal of the Washington advocacy group Ranking Digital Rights. 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. Markets continued to grapple with the economic and corporate earnings implications relating to the Russia-Ukraine conflict. “We have a ton of uncertainty right now,” said Stephanie Link, chief investment strategist and portfolio manager at Hightower Advisors. “We’re dealing with a war, we’re dealing with inflation. We don’t know what it means to earnings.” The picture was mixed overseas. Hong Kong’s Hang Seng Index fell 1.6%, under pressure from U.S. regulatory scrutiny on New York-listed Chinese companies. Stocks were more buoyant in Europe, where Frankfurt’s DAX surged 1.4%.
