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:

Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. 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. Investors took profits on Friday while they could ahead of the weekend, explained Tom Essaye, founder of Sevens Report Research. Saturday and Sunday could easily bring unfortunate news on the war front—and traders would rather be able to sell any recent winnings at Friday’s earlier prices than wait for a potentially lower price at Monday’s open. 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%. On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change.
