The original formulation of the GOR states that for the summary index of solar activity over the 11-year cycle S<italic>W</italic>, there is a close connection in pairs of an even and the subsequent odd cycles (EO), while opposite pairs (OE) exhibit no such connection. This statement strictly holds with the significance level a = 0.01, for the new version of the sunspot index SN 2.0 (Wolf numbers). In this case, an even cycle is followed by an odd one with a greater S<italic>W</italic>. For amplitudes of cycles the GOR is observed only as a trend, and the difference of connections in pairs of cycles EO and OE is statistically insignificant. The alternation of the cycle magnitude, both for the parameter and the amplitudes, is also not statistically confirmed. It has been found that various aspects of the GOR are statistically better fulfilled for the new version of the sunspot index SN 2.0, which speaks in favor of further use of this index in solar physics.</p></abstract><trans-abstract xml:lang="ru"><p>Проведено статистическое исследование утверждений, содержащихся в Правиле Гневышева—Оля (ПГО) и в некоторых его толкованиях. Показано, что ПГО в его оригинальной формулировке для индекса суммарной активности за 11-летний цикл S<italic>W</italic>, фиксирующее тесную связь в паре четный-последующий нечетный цикл (ЧН) и ее отсутствие в противоположной паре (НЧ), строго выполняется для современных наблюдательных данных — версии 2.0 чисел пятен (чисел Вольфа) — при уровне значимости a = 0.01. При этом за четным 11-летним циклом следует нечетный с большим S<italic>W</italic>. Для амплитуд циклов ПГО существует лишь как тенденция, и различие зависимостей пар циклов ЧН и НЧ статистически незначимо. Статистически не подтверждается также чередование величины циклов как для параметра S<italic>W</italic>, так и для амплитуд. Получено, что различные аспекты ПГО статистически лучше выполняются для новой версии 2.0 относительных чисел пятен — чисел Вольфа, что говорит в пользу ее дальнейшего успешного использования для исследований в солнечной физике.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Sun</kwd><kwd>solar activity</kwd><kwd>sunspots</kwd><kwd>solar cycle</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>солнце</kwd><kwd>солнечная активность</kwd><kwd>солнечные пятна</kwd><kwd>солнечный цикл</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>R.
