Dominoes Again
Like the earlier problems, Domino Magic Square and More Dominoes, this problem asks you to create a magic square. From a regular set of dominoes, remove all blanks, 5's and 6's, leaving 1-1, 1-2, ..., 4-4, 10 dominoes in all. Remove two dominoes of your choice and arrange the remaining 8 dominoes in a 4x4 grid, such that the sum of the dots in each row, column, and major diagonal is the same. Which dominoes can be removed?
