What “subset” means

Wiktionary · Wikipedia

subset/ˈsʌbˌsɛt/

  • noun(of a set S) A set A such that every element of A is also an element of S.
  • verbTo take a subset of.
Full entry on Wiktionary →

In mathematics, a set A is a subset of a set B if and only if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion. A is a subset of B may also be expressed as B includes A or A is included in B. A k-subset is a subset with k elements.

#subset across platforms

every network with a public tag surface

Follow #subset 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/subset
