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?
