Unfortunately this table suffers from a serious (printing?) mistake, placed at the level n = 6 and below, and which could be easily corrected by simply replacing the sequence of atomic numbers, Mt(109), 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, by the correct sequence of, Hs(108), Mt(109), 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120 respectively.
