Searching for the answer to the question why – in the generating of the genetic code – only mirror symmetrical left and not right amino acids (AAs) were selected, in a previous work we showed the existence of a double Boolean „triangle“ in mirror symmetry, with superposition of the top vertices: 00 -11-22 / 22-11-00 → 00-11-22-11-00 [0 as 000; 1
