A Gog-Magog Conjecture
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.
