The sets {1, 2, 4}, {11, 2, 3}, {8, 12, 2}, and {12, 4, 6} form the base blocks for a cyclic BIBD. What must the modulus be to make this true? List all of the blocks of this design.The sets {1, 2, 4}, {11, 2, 3}, {8, 12, 2}, and {12, 4, 6} form the base blocks for a cyclic BIBD. What must the modulus be to make this true?
