Reconstructions of solar–terrestrial (ST) phenomena, in sufficient quality, several thousands of years backward by means of radiocarbon (14C), 10Be or 18O isotopes have been employed for study of possible responses of the ordered (trefoil) and disordered intervals (types) of the solar inertial motion (SIM) as well as of the 370 yr exceptional segments occurring in steps of 2402 yr in these phenomena. The trefoil intervals are about 50 yr long, and the Sun returns to the trefoil intervals always after 178.7 yr, on average.……
