пишут что иногда в ряд R,C,H,O,... между кватернионами H и октонионами O уместно добавить шестимерную алгебру секстонионов S (определение на картинке; U=R^2, gl(U)=вещественные матрицы 2×2).

Например, можно определить проективную плоскость SP^2 — 12-мерное вещественное алгебраическое многообразие. Особые точки образуют RP^5, их дополнение — векторное расслоение ранга 4 над Gr(2,R^6). (а проективная прямая SP^1 — особая квадрика в RP^7)

А ещё так можно построить (не простую) алгебру Ли e_{7.5}, которая сидит между (исключительными простыми) алгебрами Ли e_7 и e_8

Telegram | DID YOU KNOW?

Date: |

This provided opportunity to their linked entities to offload their shares at higher prices and make significant profits at the cost of unsuspecting retail investors. Official government accounts have also spread fake fact checks. An official Twitter account for the Russia diplomatic mission in Geneva shared a fake debunking video claiming without evidence that "Western and Ukrainian media are creating thousands of fake news on Russia every day." The video, which has amassed almost 30,000 views, offered a "how-to" spot misinformation. Telegram has gained a reputation as the “secure” communications app in the post-Soviet states, but whenever you make choices about your digital security, it’s important to start by asking yourself, “What exactly am I securing? And who am I securing it from?” These questions should inform your decisions about whether you are using the right tool or platform for your digital security needs. Telegram is certainly not the most secure messaging app on the market right now. Its security model requires users to place a great deal of trust in Telegram’s ability to protect user data. For some users, this may be good enough for now. For others, it may be wiser to move to a different platform for certain kinds of high-risk communications. The last couple days have exemplified that uncertainty. On Thursday, news emerged that talks in Turkey between the Russia and Ukraine yielded no positive result. But on Friday, Reuters reported that Russian President Vladimir Putin said there had been some “positive shifts” in talks between the two sides. Russian President Vladimir Putin launched Russia's invasion of Ukraine in the early-morning hours of February 24, targeting several key cities with military strikes.
