Есть вот такая загадочная периодичность для квазимногочленов с "целыми" коэффициентами. Я знаю доказательство, даже расскажу, но это какая-то магия. И непонятно, есть ли профит.
(По той же схеме доказывается периодичность mod m для операций Адамса в топологической K-теории. Профиты от этой периодичности тоже не очень понимаю, но при m=2 она вроде нужна чтобы доказать инъективность J-гомоморфизма в размерностях 0,1 mod 8...)

Just days after Russia invaded Ukraine, Durov wrote that Telegram was "increasingly becoming a source of unverified information," and he worried about the app being used to "incite ethnic hatred." If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. Telegram was co-founded by Pavel and Nikolai Durov, the brothers who had previously created VKontakte. VK is Russia’s equivalent of Facebook, a social network used for public and private messaging, audio and video sharing as well as online gaming. In January, SimpleWeb reported that VK was Russia’s fourth most-visited website, after Yandex, YouTube and Google’s Russian-language homepage. In 2016, Forbes’ Michael Solomon described Pavel Durov (pictured, below) as the “Mark Zuckerberg of Russia.” Sebi said data, emails and other documents are being retrieved from the seized devices and detailed investigation is in progress. Now safely in France with his spouse and three of his children, Kliuchnikov scrolls through Telegram to learn about the devastation happening in his home country.
