такие классы симплициальных комплексов возникают вокруг теории комплексов Голода. Стрелки = вложения (все — слева направо). В пунктирных стрелках не уверен
Некоторые из этих классов имеют "самодостаточный смысл" (то есть возникают в комбинаторной коммутативной алгебре); некоторые, скорее всего, не имеют. Некоторые классы вообще "морально устарели", скорее всего (были доказаны более мощные теоремы, и потребность в них отпала). Картинку делал для себя, в ней могут быть ошибки

Telegram has become more interventionist over time, and has steadily increased its efforts to shut down these accounts. But this has also meant that the company has also engaged with lawmakers more generally, although it maintains that it doesn’t do so willingly. For instance, in September 2021, Telegram reportedly blocked a chat bot in support of (Putin critic) Alexei Navalny during Russia’s most recent parliamentary elections. Pavel Durov was quoted at the time saying that the company was obliged to follow a “legitimate” law of the land. He added that as Apple and Google both follow the law, to violate it would give both platforms a reason to boot the messenger from its stores. On Telegram’s website, it says that Pavel Durov “supports Telegram financially and ideologically while Nikolai (Duvov)’s input is technological.” Currently, the Telegram team is based in Dubai, having moved around from Berlin, London and Singapore after departing Russia. Meanwhile, the company which owns Telegram is registered in the British Virgin Islands. In view of this, the regulator has cautioned investors not to rely on such investment tips / advice received through social media platforms. It has also said investors should exercise utmost caution while taking investment decisions while dealing in the securities market. Telegram users are able to send files of any type up to 2GB each and access them from any device, with no limit on cloud storage, which has made downloading files more popular on the platform. Meanwhile, a completely redesigned attachment menu appears when sending multiple photos or vides. Users can tap "X selected" (X being the number of items) at the top of the panel to preview how the album will look in the chat when it's sent, as well as rearrange or remove selected media.
