Covering the Aztec Diamond

There are 107 non-isomorphic coverings of the Aztec diamond of order 5 by the 25 one-sided tetrasticks. In [6] Donald Knuth describes how to attack certain types of puzzles by computer. One type of puzzle he tried to solve is the covering of patterns by tetrasticks. Tetrasticks — or more general polysticks — were introduced by Brian Barwell [1]: Pieces made from a fixed number of line segments ...

Aztec Diamonds and Baxter Permutations

Abstract We present a proof of a conjecture about the relationship between Baxter permutations and pairs of alternating sign matrices that are produced from domino tilings of Aztec diamonds. It is shown that a tiling corresponds to a pair of ASMs that are both permutation matrices if and only if the larger permutation matrix corresponds to a Baxter permutation. There has been a thriving literat...
