The Gnevyshev-Ohl rule and its violations

Abstract

The 22-year cycle in the solar activity known as the even-odd effect is compared with the odd-even order. We find that the grouping into the even-odd pairs is not preferable in comparison to that of odd-even ones. We argue that due to existed relations between any adjacent cycles, combination of solar cycles in pairs according to their numbers is not justified.
