Nganou University of Oregon Journal Article 2015 10 15 A positive integer $n$ is called a CLT number if every group of order $n$ satisfies the converse of Lagrange's Theorem‎. ‎In this note‎, ‎we find all CLT and supersolvable numbers up to $1000$‎. ‎We also formulate some questions about the distribution of these numbers‎. https://ijgt.ui.ac.ir/article_13314_188efd7436d4971e7d2e54f372a19e7a.pdf
