I know. But this makes no sense, as the periodic table is, well, periodic. Elements in the same column have similar properties, at least until you get to heavier atoms. This concept doesn’t exist in math. Unless you consider isomorphism, which is well beyond the intent of this thing’s creator and too uncommon a phenomenon to merit a table (and there’s no counterpart to atomic mass in this tortured mathematical analogy- there is no periodicity).
