The perfection of the PPAASS arrangement is also reflected in the fact that when moving from the 4:6 distinctions to the 5:5 distinctions (all five and five amino acids in both decades), symmetrically arranged quantities are obtained in a new way. Admittedly, not as a mirror image of the original, but a strict "quantization", a consistent change for the second-order unit in the quantity notation (Table ). As a curiosity, or perhaps more than that, it should be noted that the first quantity is actually the sum of the first three perfect numbers (530 = 6 + 28 + 496).
