    Want to know an intuitive but valid way of making metric sets

    I just want an intuitive but valid way to describe a set S where every element in S is a coordinate (x, y, z, t) and every component is a real number multiplied by 1 standard unit of measure. This is how I'd like to describe S, but I don't know if it's too inconsistent with convention. Let Rm =...
