BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-80-829 ENTRY:: June 08, 1995 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: The dinner table problem TYPE:: Technical Report AUTHOR:: Aspvall, Bengt AUTHOR:: Liang, Frank M. DATE:: December 1980 PAGES:: 14 ABSTRACT:: This report contains two papers inspired by the "dinner table problem": If n people are seated randomly around a circular table for two meals, what is the probability that no two people sit together at both meals? We show that this probability approaches $e^{-2}$ as $n \rightarrow \infty$, and also give a closed form. We then observe that in many similar problems on permutations with restricted position, the number of permutations satisfying a given number of properties is approximately Poisson distributed. We generalize our asymptotic argument to prove such a limit theorem, and mention applications to the problems of derangements, menages, and the asymptotic number of Latin rectangles.
