Bijective mapping with tetrahedral grid of syllogisms and of coded amino acids. Red marked triangles in the left tetrahedral grid are valid syllogisms. Black framed triangles mean that the amino acid with the same colour is assigned to one syllogism. The triangles with red font are stop-sequences and are not assigned to a syllogism. The triangle with green font is the start-sequence and is not assigned to a syllogism (Gödel, DeMorgan). The other triangles with yellow font are not assigned to a syllogism in the left tetrahedral grid. They are assigned to so called invalid syllogisms i.e. darapti.
