Говорят, что плоское множество с целочисленными расстояниями есть множество полуобщего положения, если никакие три его точки не лежат на одной прямой. Известная оценка снизу для плоского множества с целочисленными расстояниями линейна относительно его мощности. Ранее не были известны отдельные оценки снизу на диаметр плоских множеств с целочисленными расстояниями полуобщего положения заданной мощности (известная конструктивная оценка сверху на диаметр плоских множеств с целочисленными расстояниями использует как раз множества полуобщего положения). В статье доказывается надлинейная оценка снизу на диаметр плоского множества с целочисленными расстояниями полуобщего положения (полиномиальная споказателем 5/4). Доказательство основано на относительно большом количестве лемм и наблюдений, включая результаты Солимоси из статьи, в которой была впервые доказана линейная оценка снизу на диаметр плоских множеств с целочисленными расстояниями.</p></abstract><trans-abstract xml:lang="en"><p>A point set 𝑀 in the Euclidean plane is said to be a planar integral point set if all the distances between the elements of 𝑀 are integers, and 𝑀 is not situated on a straight line.A planar integral point set is said to be a set in semi-general position, if it does not contain collinear triples. The existing lower bound for mininal diameter of a planar integral point set islinear with respect to its cardinality. There were no known special diameter bounds for planar integral point sets in semi-general position of given cardinality (the known upper bound forplanar integral point sets is constructive and employs planar integral point sets in semi-general position). We prove a new lower bound for minimal diameter of planar integral point sets insemi-general position that is better than linear (polynomial of power 5/4). The proof is based on several lemmas and observations, including the ones established by Solymosi to prove the first linear lower bound for diameter of a planar integral point set.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комбинаторная геометрия</kwd><kwd>диаметр множества</kwd><kwd>множество с целочис- ленными расстояниями.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>combinatorial geometry</kwd><kwd>diameter of a set</kwd><kwd>integral point set.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект 19-11-00197).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Anning N.
