10 posts held, back to 11 June 2026 — 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 pageof Telegram’s post history, 20 posts per page.
ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.
Lifetime counters from Telegram’s own channel header, read 8 August 2026 — not the date at the top of this page, which is when the subscriber count was last read. Below Telegram’s rounding threshold, so these counts are exact.

В этом году команда участвовала очно, без ограничений. Отдел…
Появились результаты Международной олимпиады по математике: https://www.imo2026.com/Results/Individual_Results.htm 4 золота, 2 серебра, 3 место в командном зачёте. Особенно радостно за Арину Прокудину (41 из 42 баллов!) - очень вдохновляет :)
Педагог 15 стобалльников ЕГЭ-2026: «Я не готовил к экзамену, а учил думать» Учитель лицея №131 Казани Кирилл Сергеев подготовил сразу 15 стобалльников по профильной математике – это лучший результат в Татарстане. Но сам педагог считает, что говорить нужно не о рекордах, а о многолетней работе с детьми, любопытстве, умении рассуждать и доверии между учителем и учеником. https://www.tatar-inform.ru/news/pedagog-15-st…
Я думаю, многие сталкивались с тем, что школьный этап ВСОШ пройти нелегко: дети пишут его дома, поэтому, к сожалению, не всегда честно. Сильные ребята, которые решают сами, порой не проходят в следующий тур, а среди прошедших много около нулевых результатов. Мне кажется, сгладить ситуацию помогали персональные приглашения. Сейчас их хотят отменить. Если для вас вопрос важен - есть возможность отреагировать на закон…
Коллеги, школьники и их родители, готовится новый порядок проведения ВсОШ. Здесь можно ознакомиться с проектом https://regulation.gov.ru/projects/169275/ Сейчас в проекте предусмотрена отмена персоналок на всех этапах олимпиады, начиная с перехода со школьного на муниципальный. Если вы не согласны с такими изменениями, можно поддержать обратную связь: — поставить дизлайк; — оставить содержательный комментарий пр…
🏆 Сегодня в Шанхае стартовала 67-я Международная математическая олимпиада — IMO 2026, главное школьное математическое соревнование в мире. Публикуем условия задач первого дня. Завтра выложим второй.

Впервые с матбоями я познакомилась на первом курсе университета. Кажется, тогда я не могла решить ничего или почти ничего. Мы играли с четверокурсниками, и, вероятно, моя команда тот турнир проиграла — результат память не сохранила. Но навсегда запомнилось другое: матбои — это ни на что не похожее волшебное действо. Они завораживают, влюбляют, вызывают зависимость и заставляют расти. В этом году родилась идея прове…
Если вы закончили школу в этом году или много лет назад и с теплом вспоминаете учителя или педагога кружка по математике, физике или информатике, сейчас есть хороший способ сказать спасибо. Т-банк проводит опрос, в котором выпускники могут порекомендовать педагогов, которым они благодарны https://polls.tbank.ru/s/cm71sk7nb00fu0etvgbxx1y6v. Учителей, получивших больше всего таких рекомендаций, пригласят на онлайн-инт…
На Турнире Талантливых Математиков в Санкт-Петербурге едим вместе пуд соли (конфет, задач), учимся, а в свободное время знакомимся с летней стороной северной столицы:)
Showing the 10 most recent of 10 posts we hold for @extra_tasks. 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.
Citation-graph rank — 413,542 of 1,160,990entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
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.
Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
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.
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 8 August 2026 — this entry's latest reading, not the date you are reading this.
