A Gog-Magog Conjecture

(5 pages)

Abstract. We present a conjecture relating magog trapezoids to gog trapezoids. This generalizes a conjecture due to Mills, Robbins and Rumsey [J. Combin. Theory A 42 (1986), 277-292]. In the second part of this note, we show how to simplify Act I of Zeilberger's celebrated proof [Electron. J. Combin. 3 (no. 2, "The Foata Festschrift") (1996), Art. #R13] of the alternating sign matrix conjectre.
