7 posts held, back to 26 May 2025 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 7 posts for this entry, the most recent from 12 September 2025. An engagement rate over an empty window would be a number about nothing.
68 reactions across 6 posts, in 9 distinct kinds. The most used accounts for 29.4% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 6 of the 7 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 68 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 7 most recent posts we hold, published 26 May 2025 to 12 September 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.
📞 ОТКРЫТЫЕ УРОКИ по школьной и олимпиадной математике | 12–14 сентября Мы хотим пригласить ребят и родителей на открытые уроки от наших друзей из PhysX. Это возможность попробовать интересные темы математики и познакомиться с преподавателями в спокойной и доброжелательной атмосфере. Когда: 12–14 сентября Для кого: ученики 3–9 классов На уроках будем вместе разбирать полезные приёмы, решать необычные задачи и смот…

Группы по программированию от ИТД + МММФ! Как быстро летит время. Подходит к концу очередное лето. Ребята, которые на моих глазах только начинали свой олимпиадный путь, переживали из-за матпраздников и уртюмов, уже давно всеросники; другие, приходившие на зрелой части олимпиадного пути и с огнём в глазах, стремящиеся к заветному победству, уже перелистнули олимпиадную страницу своего пути, учатся в университете и по…

Мы с коллегами из PhysX запускаем летние кружки по математике! На кружках мы реализуем очень крутую систему — Катакомбы. За решение задач ребята будут получать жетоны, которые можно тратить, чтобы продвигаться по виртуальной карте и получать призы, бонусы и разный мерч. Будут группы: • 5-8 классы — олимпиадная математика • 5-7 классы — школьная математика Первая неделя будет пробной, чтобы каждый мог бесплатно п…

🌀 Этим летом я читаю восьминедельный курс по теории вероятностей — для тех, кто хочет впервые разобраться в материале или заново выстроить его с нуля Это расширенная версия курса, который я читал на Тьюринге, в 179-й школе и буду вести на школе «Лес». Уровень — как у вводных курсов по высшей математике: без чрезмерных упрощений, но вполне доступно 🔍 Курс устроен как цепочка исследовательских вопросов, в которых слу…

Наши друзья из Кроссворда Тьюринга запускают онлайн курс по теории вероятностей! Приглашаем вас присоединиться!)
Всем привет! На связи Игорь Почепцов. В новом учебном году я участвую в нескольких математических проектах: продолжаю вести кружки, запускать матигры и другие форматы. Один из новых проектов — PhysX, где я буду руководить математическим отделением. Вместе с командой мы уже разрабатываем занятия для 5–8 классов. 🔥 Сейчас мы запустили бесплатную диагностику по школьной и олимпиадной математике. Она подойдёт ученикам…

Showing the 7 most recent of 7 posts we hold for @itd_math. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Republishes
Channels on the register whose posts this channel has forwarded.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
The reverse of the list above, and a different kind of signal. This does not require this channel to have ever been asked about directly — each row below is a channel we DID ask Telegram about, whose Telegram-generated list happened to include this one. A channel can appear here with an empty list above it, because being named by someone else’s query is independent of having been queried itself.
This channel appears in 1 seed channel's Telegram-generated recommendation list in total. Each is Telegram’s list for THAT channel, not this one — see how this is measured.
A live page changes as we take new readings, so a citation should name the measurement it is based on, not just the URL. The line below cites the subscriber count as measured 13 September 2026 — this entry's latest reading, not the date you are reading this.
