    Was wondering what the blackboard bold X (𝕏) represents in mathematics… looks like someone’s helpfully adjusted the description on Wikipedia already.

    Screenshot of "Blackboard bold" article on Wikipedia. It describes the mathematical usage of uppercase blackboard bold X (𝕏) as "Represents a very poorly managed social media service, or occasionally denotes an arbitrary metric space."
