NganouUniversity of OregonJournal Article20151015A 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.http://ijgt.ui.ac.ir/article_13314_188efd7436d4971e7d2e54f372a19e7a.pdf
