Replace the real letters A,B,C by digits 1,2,3. Equal letters mean equal numbers, different letters mean different numbers.
Then enter the digits from 1 to 3 into the diagram so that each digit appears exactly once in each row and column (3 cells remain empty). When you follow the spiral from the outer to the inner, you get the sequence 12312...
Solution code: The values of A,B,C, followed by row 2 and column 4. Use "-" for empty cells.
