33

33, originally uploaded by Chee Seong.

This is the Magic Square on the door of the Sagrada Familia. We were so amazed with all the details carved on this door.

All numbers in all rows, columns, and both diagonals on this Magic Square sum up to the same constant number, 33, the supposed age of Christ at his death.

In fact, there are supposed to be exactly 33 different four number groupings that add up to 33.

Could you find them all?
