🌗 自然數集合格的豐富結構 ➤ 探索自然數冪集格中隱藏的無限偏序宇宙 ✤ https://jdh.hamkins.org/the-lattice-of-sets-of-natural-numbers-is-rich/ 本文探討自然數冪集偏序格 $\langle P(\mathbb{N}), \subseteq \rangle$ 的豐富結構。作者證明了該偏序格具備通用性，能嵌入任何可數偏序關係。透過將任意可數偏序集中的元素映射至其前趨元素（向下集）在自然數中的索引集合，作者成
#可數偏序 across platforms
every network with a public tag surfaceFollow #可數偏序 straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.
Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/可數偏序
