Enumeration of Rectangles in a Tableau Shape
Mingus, Tabitha T. Y.; Grassl, Richard M.; Diaz, Ricardo; Andrew, Lane; Parker, Frieda
Mathematics Teacher, v103 n9 p693-698 May 2010
This article analyzes the challenge of counting the number of rectangles of all sizes in the n-tableau and to provide a combinatorial reason for the answer. The authors present a solution on enumerating rectangles in the n-tableau using Grassl and Mingus results. The authors demonstrate their conjecture for the n-tableau and attempt to apply their rule of work for tableaus of other sizes. The authors stress that several interesting combinatorial identities are by-products of their rectangle count. (Contains 9 figures and 2 tables.)
