    Yeah, we gonna need more rigor on this one.

    “A square is a shape made up of four equally long lines a, b, c, d where a is perpendicular to c and d and parallel to b. Each of these lines meet exactly two other lines at it’s ends.”

    I’m not a mathematician so there might an odd case somewhere in there. Maybe it has to be confined to a shared plane?

      Lines are infinitely long… do you mean line segments?

      Wikipedia has a good enough definition: “It has four straight sides of equal length and four equal angles.” Nice and simple.

      So you’re saying this is the outline of a square in the astral plane? Because it sounds like you’re saying this is a square in the astral plane.
