Золотарева, получен аналог квадратичного закона взаимности для групп с использованием символа Кронекера. В нашей заметке предложено короткое доказательство этого утверждения с использованием символа Якоби. Работа в основном носит методический характер. В связи с этим в ней также приведено доказательство результата установленного в работе Фробениуса (1914), связанного с комбинаторной интерпретацией символа Якоби.</p></abstract><trans-abstract xml:lang="en"><p>In the paper of Duke and Hopkins (2005), following the approach of E.I. Zolotarev, an analogue of the quadratic reciprocity law for groups was obtained using the Kronecker symbol. We present a short proof of this statement using the Jacobi symbol. The work is mainly of a methodological nature. In this regard, we also provide a proof of the result established in the paper by Frobenius (1914), related to the combinatorial interpretation of the Jacobi symbol.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>символ Якоби</kwd><kwd>квадратичный закон взаимности</kwd><kwd>характеры</kwd><kwd>конечные поля</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Jacobi symbol</kwd><kwd>quadratic reciprocity law</kwd><kwd>characters</kwd><kwd>finite fields</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">W.
