We show that the number of configurations of the 20 Vertex model on certain domains with domain wall type boundary conditions is equal to the number of domino tilings of Aztec-like triangles, proving a conjecture of the author and Guitter. The result is based on the integrability of the 20 Vertex model and uses a connection to the U-turn boundary 6 Vertex model to re-express the number of 20 Vertex configurations as a simple determinant, which is then related to a Lindström-Gessel-Viennot determinant for the domino tiling problem. The common number of configurations is conjectured to be 2n(n−1)/2 ∏n−1 j=0 (4j+2)! (n+2j+1)! = 1, 4, 60, 3328, 678912 . . .. The enumeration result is extended to include refinements of both numbers. Mathematics Subject Classifications: 05A15, 05B45, 82B20, 82B27
