22 posts held, back to 17 April 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 16 pagesof 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 13 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.
936 reactions across 22 posts, in 12 distinct kinds. The most used accounts for 40.0% 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 22 of the 22 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 936reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 22 most recent posts we hold, published 17 April 2026 to 11 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Геометрический лекторий Спешу сообщить всем читателям нашего канала, что на этой неделе стартует лекторий по геометрии, в котором я тоже принимаю участие. Это открытые и бесплатные лекции замечательных авторов для сильных школьников по совершенно разным темам от неравенства треугольника и построений циркулем и линейкой до эллиптических кривых и геометрии Лобачевского. Кроме лекций будет несколько спецкурсов с прове…

Концерт в галерее Середина лета уже миновала, а лето — это не только математика и задачи, но и сосны, земляника, малина и смородина. Это еще и костры, дымный чай, фестивали и песни. А тех, кто остался в это время в Москве, в эту пятницу я приглашаю на свой концерт в художественную галерею Minima — она находится недалеко от станции метро Новослободская. На этот раз я буду играть один. Без ансамбля. И вход будет шляпн…

Т- образование На прошлой неделе я прочитал лекцию для учителей - победителей конкурса Т-образования по математике и физике. Рассказывал о том, что математика - это часть натуральной философии, то есть философии природы, на современном языке - физики. Конечно, говорил я и о своих новых учебниках по геометрии. Оказывается, многие учителя в регионах ими уже вовсю пользуются. Не скрою - это очень приятно узнавать. Встр…

Прямой угол от Фаберже Еще Фалес из Милета заметил, что диаметр круга виден из любой точки на его границе под прямым углом. Новая задача из канала Фулл и точка является красивым обобщением этого факта. Разрежьте круг на сегменты по хорде, перпендикулярной диаметру АВ, и поверните их вокруг конца этой хорды. Пусть М - середина отрезка между другими концами сегментов. Тогда угол АМВ будет всегда прямым. Анимацию к это…

Проекция пирамиды Этим летом я пишу курс стереометрии 10 класса. И неизбежно придумываю упражнения и задачки на разные его темы. Вот пример такой, как мне кажется, довольно простой задачи. На рисунке показана ортогональная проекция правильной пирамиды. Как по ней определить углы между гранями этой пирамиды?

Центр между высотами Предлагаю задачу на исследование. Центр описанной окружности треугольника редко лежит на отрезке между основаниями двух его высот. Такое может произойти, когда угол между сторонами, на которые опущены эти высоты, попадает в диапазон меньший 7 градусов. Какой это диапазон? И пока открытый вопрос: могут ли длины всех сторон такого треугольника быть целыми числами?

Завтра ЕГЭ Завтра школьники России пишут профильный экзамен по математике. В качестве последней тренировки я предлагаю всем решить хорошую задачу в его стиле. Когда-то я давал ее на исследование восьмиклассникам в школе Летово. А еще я желаю всем завтра удачи!

Круги в шестиугольнике Предлагаю задачу, которую можно решить методами 8 или даже 7 класса. Этот факт я обнаружил случайно и решил им с вами поделиться. Попробуйте найти его доказательство без расчетов и теоремы Пифагора.

ЕГЭ + Вот одна из самых красивых моих задач в стиле Единого Экзамена. Как часто бывает, она сложнее, чем для него нужно, и больше подходит для разных Олимпиад. Тем не менее, я хочу с вами ей поделиться - пусть ученики математических классов немного поломают над ней голову:)

ЕГЭ Предлагаю всем свою новую задачу в формате Единого экзамена. На этот раз она по сложности соответствует боевым задачам экзамена и, что также не маловажно, имеет хороший ответ. Постарайтесь его найти:)

ЕГЭ Предлагаю очередную задачу для тренировки в формате Единого экзамена. На глаз кажется, что на данном рисунке одновременно отрезок PN параллелен катету ВС и равны отрезки АМ и СМ. Как верно заметил Константин Кноп, этого не может быть. Почему же такой рисунок кажется правдоподобным?

Showing the 12 most recent of 22 posts we hold for @volk_geometry. 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 — 239,744 of 1,169,250entries 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.
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
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 3 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.
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.
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 August 2026 — this entry's latest reading, not the date you are reading this.
