COMMPUTATION!!!

This solve is really simple, it is separated into two part, first, it dupes the atom if its a elemental, then tries to turn it into a fire. After that, it tries to triplex, which determines if its a metal or elemental. It then outputs the elemental.

If the output is a metal though, it passes the metal to be promoted, and it writes the opposite of promotion # onto a hex arm with quicksilver, it then promotes a piece of lead with the said quicksilver. Some optimizations were made to turn it into full 6p and yeah.
